There's an (almost obvious) secret to making quantum leaps in your understanding about a subject VERY FAST - at least the theory/intellectually.
You can't do without it if you want to be world class at something, so this is also an overpowered hack for developing skills, too.
The Pareto'd version of this is to pick either 2-5 books about the topic, depending on your level of dedication. The key is to pick the books well (get help from AI w this, or ask on a forum/an expert, etc - they'd usually know). Assuming you'll read 3 books, this should be the team:
1. First book should be the "best" book that's widely known, if you ask anyone practising this, they'd tell you to read this one about it. Right edition of the canonical textbook, or the field founder's primary book, etc all go here. Most papers or people would reference this, etc. You know the one. Read it & read it well.
2. Second book is more like a "practitioner's guide" type thing. If it's an old field, you might want to read however the new experts are approaching it, one of the "new canon" books could go here. I really like "teacher's guide" type of books, here. How to teach X to people, groups, how to practice this, secrets of X, what I would've done differently if I started X again, rare talks to the initiated, etc. Very valuable.
3. Third book is the "underground" type. Most fields either have a "wizkid who went dark" type story, or a practitioner who became anti, or some groundbreaking book that tells the inner secrets of the field, maybe a correspondence compilation, fringe book about this, whatever. Find the dark sheep book and read that one.
These 3 types should give you an almost-360 view of the whole field, the whole thing and different perspectives in it. You'd probably have lesser, but harder to answer questions about the field.
If this is something that can be practiced, a skill etc, ideally you'd practice alongside w the reading so you could have a much better understanding. Coming up with hypotheses, different experiments, trying moonshots or unlikely things, etc should all accompany the process if you want to make real leaps.
Obviously the "hours put in" is the most important metric to begin with, but the real multiplier there is if you can attack it from all angles and make it fun and interesting. So, ideally you'd maximize the exploration/fun/interestingness/angles count with the intensity/reps count, and so on.
The weird thing, since no one really cares almost anything that deeply nowadays, is that once you go through this process, you'll have a hard time finding people you can actually relate to, in the field. You'll see people getting PhDs and have "practising for the past 40 years" and haven't made ANY real leaps except some tiny grain sized and you'll feel "What have you been doing?!" - but you'll get along very well w the actually passionate people doing this, which is the point anyways.
And maybe I should've written this at the top, but it's critical and no one does this: Before you pick a skill or a topic, unless you feel absolutely called to and/or it's absolutely clear to you - just ask yourself, what do you want out of this? And really inquire into it. Ask around, etc.. Because there might be another, easier way(s) to get that thing. This is the highest leverage and easiest shift to make, and if you get this wrong, it's the costliest. So you have to run that script every single time.

The more I look at the economics of AI infrastructure, the more convinced I become that one of the most popular bear arguments against the AI capex cycle is beginning to weaken, because the market has spent the last two years assuming that GPUs are effectively brutally depreciating assets with extremely short economic lives, where every new NVIDIA generation supposedly renders the previous one obsolete and leaves hyperscalers and neoclouds holding stranded hardware, yet the data in these charts suggest something much more interesting is happening, with older GPUs maintaining or even improving rental economics, inferred residual values remaining surprisingly resilient, and this occurring at exactly the same time that the end-user cost of AI, measured through token prices, is falling sharply.
That combination matters enormously because if the bear case were correct and every new generation of GPUs immediately destroyed the value of the previous generation, then we should already be seeing H100, A100 and H200 rental rates collapse as customers migrate toward newer hardware, secondary-market values deteriorate and utilization falls, yet the opposite appears to be happening, with H100 residual values recovering toward roughly US$30,000, H200 values around US$38,000, A100 values still holding near US$18,000, while B200 rental rates remain extremely strong around US$5.69 per GPU-hour, H200 around US$3.29, H100 around US$2.63 and A100 around US$1.59, which is not what an oversupplied or rapidly obsolescing market is supposed to look like.
What makes the second chart even more interesting is the overlay with the token price index, which has fallen dramatically from above US$2 per million tokens toward roughly US$1, meaning that the cost of consuming intelligence is declining at the same time that the productive value of the hardware producing that intelligence remains resilient, and I think this is the point that many investors are still missing because falling token prices are often interpreted as evidence that AI economics are deteriorating, when in reality they may instead be evidence that AI is becoming dramatically more efficient while usage grows even faster.
This is the same pattern we have seen repeatedly throughout the history of technology, where storage became cheaper and the world responded by storing exponentially more data, bandwidth became cheaper and people responded by streaming more video, compute became cheaper and companies responded by building more software, and now intelligence itself is becoming cheaper, which means the natural outcome may not be that the world spends less on AI but rather that the world consumes far more intelligence because the number of economically viable applications expands every time the cost of inference falls.
That is why I think investors need to be careful when they look at AI hardware through the lens of traditional server depreciation, because older GPUs do not necessarily become useless when a new generation arrives, particularly when the underlying demand for compute is expanding much faster than new supply can be installed, which means the market can evolve into a hierarchy where the newest GPUs are allocated to frontier training and the most compute-intensive reasoning workloads, the previous generation migrates into mainstream inference and fine-tuning, and older generations continue serving enterprise workloads, batch processing, smaller models and latency-insensitive tasks.
The best analogy may actually be aviation rather than smartphones, because a new Boeing 787 does not suddenly make every 777 worthless, and while the newer aircraft may be more fuel efficient and better suited to certain routes, the older aircraft can still generate attractive returns if demand for air travel remains strong enough, which is increasingly how AI compute appears to be behaving, with Blackwell not necessarily killing Hopper, Hopper not necessarily killing Ampere, and each new generation instead creating a new upper tier while the older hardware cascades downward into other economically useful workloads.
That is not instant obsolescence. It is segmentation. And segmentation matters because it expands the total market by allowing different classes of hardware to serve different levels of workload intensity, which means that if aggregate AI demand continues to grow faster than aggregate compute supply, then every layer of that hierarchy can remain valuable even as the frontier keeps moving forward.
This is exactly why the rental-rate data are so important, because H100 pricing stopped declining and began recovering, A100 pricing stabilized, H200 economics strengthened and B200 pricing remained strong, all of which suggest that the market is not experiencing widespread compute oversupply but rather continued absorption across generations, and if that interpretation is correct, then one of the key arguments behind the AI capex bear case, namely that hyperscalers and neoclouds are overbuying GPUs that will become economically obsolete before earning back their capital cost, begins to look much less persuasive.
The useful economic life of these assets may simply be longer than the pessimists assume, and even more importantly, the payback period may be materially shorter than the depreciation period, which is the combination that actually matters for capital returns because if a GPU costs US$30,000 but can generate thousands of dollars of monthly rental revenue at high utilization, the owner can recover a substantial portion of the original investment long before the hardware becomes economically irrelevant, meaning that whatever residual value remains after payback becomes optionality rather than a prerequisite for achieving an acceptable return.
That is a fundamentally different economic setup from buying an asset that loses most of its value before it has generated sufficient cash flow, and this distinction becomes particularly important when evaluating the hyperscalers, because Microsoft $MSFT, Amazon $AMZN, Alphabet $GOOG and Meta $META are all spending extraordinary amounts on AI infrastructure while investors continue to ask whether this capex eventually becomes stranded, yet if older GPUs retain economic usefulness while newer hardware commands premium workloads, then the effective return on invested capital could turn out to be much better than simplistic depreciation assumptions suggest.
This is also why I think investors should stop treating falling token prices as automatically bearish for AI infrastructure, because the relationship between price and revenue is not linear, and a 50% decline in token price does not mean AI revenue necessarily falls 50% if the lower price causes usage to increase fivefold, particularly as AI usage moves away from simple chatbot interactions toward agentic workflows that can consume orders of magnitude more compute because they reason across multiple steps, search, call tools, retry, verify outputs, coordinate with other agents and maintain memory.
A simple chatbot interaction may require only a few thousand tokens, while an autonomous agent performing a complicated workflow could eventually consume hundreds of thousands or millions of tokens as it iterates through a task, which means the move from chatbots to agents can massively increase aggregate token consumption even while the cost per token continues falling, and this is why I think the right metric to watch is not price per token but total useful intelligence consumed.
That is the more important economic variable because enterprises do not ultimately care about tokens in isolation, they care about whether the output creates more value than it costs, and if an AI agent can perform a task for US$2 that previously required US$50 of human labor, then the economics are still extraordinary even if token prices fall by another 50%, while that lower cost actually unlocks new workflows that would previously have been too expensive to automate and expands the addressable market further.
This is why deflation at the unit level can coexist perfectly well with a massive boom at the aggregate level, because semiconductor cost per unit of compute fell for decades while semiconductor demand exploded, storage cost per gigabyte collapsed while global data generation became enormous, telecommunications cost per bit fell while internet traffic multiplied, and AI could follow the same path except that what is becoming cheaper is not simply storage or bandwidth but intelligence itself, which could make this one of the most economically important cost curves of our generation.
The GPU residual-value data are also important from a financing perspective because if lenders, infrastructure investors and private-credit providers become more confident that GPUs retain meaningful residual value rather than becoming near-worthless after a short period, then the cost of capital for AI infrastructure can decline, since a bank financing a GPU cluster cares enormously about what the underlying hardware is worth in a downside scenario, and there is a huge difference between assuming that a US$30,000 GPU will be worth US$5,000 after two years and assuming that it can still be rented profitably or sold for US$15,000.
The second scenario produces a much stronger collateral profile, which can support lower financing spreads, higher advance rates and larger pools of capital, which in turn supports more infrastructure buildout, more model development, more inference capacity and ultimately more AI applications, creating a reinforcing flywheel where stronger residual values make the financing of compute easier while greater availability of compute helps expand the market for intelligence.
This is particularly relevant for neoclouds and GPU infrastructure providers, where much of the bearish thesis depends on the idea that they are funding short-lived assets with long-duration liabilities, because if the assets retain economic value for longer than expected, the asset-liability mismatch becomes less severe, even though utilization, customer concentration, financing costs and power availability still remain critical risks.
The same dynamic strengthens NVIDIA’s strategic position because if customers believe its GPUs retain stronger residual values, then the effective total cost of ownership falls, which means the willingness to pay for new generations can actually remain high even as NVIDIA continues releasing better hardware, and this is where the annual product cadence can become bullish rather than cannibalistic, because the conventional bear argument says a new architecture every year accelerates obsolescence while the alternative view is that the newest architecture takes the highest-value frontier workloads, the previous generation migrates into mainstream inference and older hardware finds lower-cost applications where it still generates cash.
Again, that is not obsolescence. It is a cascading compute stack. And if demand is expanding fast enough, the stack can keep growing even while every individual generation becomes less cutting-edge over time.
That said, I would not take the charts at face value without caveats because the residual values here are inferred from rental rates rather than actual realized secondary-market transactions across a deep and liquid resale market, while rental rates themselves can be influenced by temporary shortages, regional constraints, specific configurations, cluster topology, power costs, networking quality and utilization, which means a GPU sitting idle in the wrong data center is not economically equivalent to the same GPU operating inside a highly utilized, well-networked cluster.
Compute is not merely the chip. It is the chip plus networking, power, cooling, orchestration, software and customers.
That is why utilization remains the key risk, because if AI demand were to disappoint materially and large portions of the installed base became underutilized, rental rates and residual values could fall very quickly, which means the bullish interpretation depends fundamentally on continued growth in economically useful workloads rather than on the hardware itself possessing some magical immunity to depreciation.
But that is also why the current trend matters so much, because if we were already in a severe AI infrastructure bubble with widespread overcapacity, I would expect the oldest hardware to be collapsing first, yet instead H100, H200 and even A100 economics remain resilient while token prices continue declining, which suggests the industry is becoming more efficient without simultaneously destroying demand for compute.
That is an unusually bullish combination because it means cheaper intelligence is not translating into weaker hardware economics but into broader adoption, higher utilization and stronger aggregate consumption, which is exactly what you would expect to see if the demand curve were shifting outward faster than the cost curve were moving downward.
Cheaper intelligence. More applications. More agents. More inference. Higher utilization. Resilient rental rates. Stable or rising residual values. New generations commanding premium pricing. Older generations remaining economically useful. That is not what the end of a capex cycle looks like. It looks much more like an industry moving down the cost curve while the market for its output expands even faster.
This is why I remain bullish on AI stocks, because I do not believe every company associated with AI will win, I do not believe every data center project will earn attractive returns, I do not believe every neocloud will survive, and I certainly do not think valuation can be ignored, but I increasingly think the core infrastructure thesis remains intact because the market continues to underestimate how much compute the next generation of agents, reasoning systems and autonomous workflows could consume.
The bear case assumes rapid technological obsolescence, while the data increasingly point toward persistent economic usefulness.
The bear case assumes falling token prices destroy AI economics, while I think falling token prices expand the market.
The bear case assumes hyperscalers are overbuilding capacity, while I see older GPUs retaining value even as newer hardware is being installed at record speed.
The bear case assumes saturation is approaching, while I think we are moving from a world where humans occasionally chat with models toward one where billions of software agents consume intelligence continuously in the background.
That is a completely different demand curve.
So my takeaway from these charts is relatively simple: AI compute is getting cheaper at the unit level while becoming more valuable at the system level, and that is not a contradiction but exactly what happens when a technology becomes economically transformative, because lower costs unlock more use cases, more use cases create more consumption, more consumption supports higher infrastructure utilization and higher utilization preserves the value of the hardware.
If intelligence follows the same path as bandwidth, storage and compute before it, where unit costs collapse while aggregate consumption explodes, then the biggest risk for investors may not be that the world has already built too much AI infrastructure.
It may be that we are still underestimating how much intelligence the world will eventually consume.
Long AI.

I used to be a chronic procrastinator and it left me an absolute shell of a human. doing things immediately and with intense urgency was truly the cure. you think of an idea and you write it down instantly. you think of someone and you text them on the spot. even a mundane task like putting your laundry away gets done the second it appears. stop leaving things for later. just do it now

incredible quote from Snowball
"They asked [Buffett] what had been his greatest success and greatest failure. He didn’t tell them about his business mistakes of omission this time. Instead he said:
“Basically, when you get to my age, you’ll really measure your success in life by how many of the people you want to have love you actually do love you. I know people who have a lot of money, and they get testimonial dinners and they get hospital wings named after them. But the truth is that nobody in the world loves them. If you get to my age in life and nobody thinks well of you, I don’t care how big your bank account is, your life is a disaster."

on reading habits... the way I'd break it down to my 23-year old self
arguably the most important thing to get right in determining the trajectory of ur life
1/5
first priority, u gotta master whatever is needed for work + reach the highest level of proficiency...this is not limitless, somewhere in the 5-10 year range u should be "finished"
lets say ur done with most work days at 7-8ish
on two or three weeknights, when u arent being social, u can knock out 1-2 hours of reading
go out friday night + either saturday day or sunday day, and block off the other day as "work" (usually sunday)
if ppl are out u say "I can't make it, I have to work," which is true in the sense of...ur working because u want to win. and reading always falls under the bucket of work
after u do whatever actual work u need to do, u knock out 3-5 hours reading
the compounding of these days, and weeknights, is what creates a massive difference over a decade
2/5
once u no longer suck at ur job / are done with that reading, u start mixing in stuff like top novels of all time, classics, history
but really u want to focus on "The Eminent Dead" as Munger calls them
great man bios, heroes, conquerors, leaders, all the way back to the Greeks and Romans
u want to build relationships with them, where u develop their collective voices in ur head, and let their advice be what guides u through life.
I didn't understand this until say 35 but it could've been useful at 25
3/5
uploading the "eminent dead" is how u become a leader and exercise independent judgement, rather than blindly following the crowd
u will quickly realize that most people have no fucking clue what they're doing, a lot of opinions are just mechanically repeating what they were told
if u ask ppl "why do u believe what u believe?" they freeze up
and in following the footsteps of the eminent dead, u will recognize that there is a wide divergence in what they would do vs. what the crowd u see around u is doing..."this isn't right, this isn't how all the heroes throughout history would act."
everything great comes from having courage in ur own convictions + from a willingness to say, "I see everyone going that way, but I know that the correct thing to do is go this way"
over time, people will pick up on that u have some clue what ur doing, and they will start following u
4/5
on social media, u mostly want to leave this shit alone
all it does is slopbeam "crowd habits" into ur brain rather than the habits of the eminent dead, which u would get from books
these forums are best used for getting "reps" in writing, in creativity, evaluating ur ideas, and getting feedback
stay as far away as possible from the gossip section, or passing judgment on random finance/tech "celebrities" who u will never meet and have no bearing on ur life
when ur young, u will see the crowd doing it and u will blindly do what the crowd does so u can "fit in"
u will make an anonymous account and talk about how stupid terry smith is, despite that he runs 12 billion, and ur unemployed daytrading a $25k robinhood account
as u read more u will see that the Eminent Dead are unanimous on critics...loathed, held in contempt, viewed as cowards, and criticism in general is viewed as a massive waste of time, i.e. "great minds talk about ideas, small minds talk about people"
when u look back at the time u spent engaging in it, u will realize they were right. u never gain anything in bringing others down, every single minute is an 100% pure waste of time
u will learn that u can read people very quickly based on what they talk about, because people talk about what they think about, and people think about whatever they upload
for some that's books, for others its gossip
but for all, the output will always reflect the input... because "what you focus on expands."
5/5
as long as u block off these weekly hours, and u keep a stack of 10 books around, ur gonna be good
u can have several genres going - few novels, few bios, few history books, few psychology/philosophy, etc
because ur mood will change, ur attention span is variable, and some books require deeper concentration than others
biographies tend to be a heavier lift, whereas any novel written in the last 50 years... u can be tired and hungover and still rip through it
read what appeals to u, dont worry about what everyone else thinks, never force anything
some writers or individual titles inevitably just wont click for u
there's no rhyme or reason, I don't like Dickens, I don't like Dostoevsky, I like Tolstoy, I like some Thomas Mann, but not all....is this how it's "supposed" to be, I don't know and don't care
u read these books to try and figure out how this life shit actually works. there is no "supposed," a book is either helping u or it isnt
if one isn't working for u, just give it to a friend and keep starting new books until one "clicks," it always will
END
that's all there is to it
if u read a lot, u will never in your life know what "boredom" or "loneliness" feel like
every problem u will ever face, there is a book written on how to either solve it, or how to navigate it while keeping ur head about u
and if a book shifts ur worldview, and u suddenly recognize u have the wrong ppl around u, trust ur gut and change what needs to be changed
the eminent dead will never steer u wrong
will end this with a letter that John Adams wrote to his son:
--
"Read somewhat in the English poets every day. You will find them elegant, entertaining and instructive companions, through your whole life.
To one who has taste, the poets serve to fill up time which would otherwise pass in idleness, languor, or vice. You will never be alone, with a poet in your pocket. You will never have an idle hour.
How many weary hours have been made alert, how many melancholy ones gay, how many vacant ones useful, to me, in the course of my life, by this means?"
- J. Adams
Amsterdam, May 14th, 1781
The science of neuroplasticity is amazing.
You are not who you think you are.
You are not shackled in your ways.
You are not your defaults.
All of these neural pathways can change. The way you view the world can change completely.
All you have to do is put the effort in to change the pathways that you and your environment have created over all the years of your life.
It’s never too late to start again.
It’s never too late to change.
It’s never too late to be who you want to be.

I’m convinced that the most important skill in life is the ability to just figure it out. You’ll face a lot of problems that you have no idea how to solve. There’s nothing more valuable than knowing you’ll see it through. That you’ll handle it. Do the work. Get it done. Repeat.
