For decades, we called it the Indus Valley Civilisation. But archaeology, palaeochannel mapping, geology and satellite imagery point to a wider, maybe clearer picture: the Sindhu–Sarasvati Civilisation. A thread on a civilisation, a river, a script and a narrative worth re-examining. 🧵1/21

People outside the AI labs should have a real say in how this technology develops, and a clear way to judge if it's happening safely. Standards should help prevent the concentration of power, including by making sure new companies and open-model companies can compete. They should also help countries and companies compare evidence and learn from failures. We think the US should lead this effort. Here is our proposal: openai.com/index/building-st…

Mesopotamia was never the cradle of civilisation. India was. I spent forty years in international shipping, not academia. When I began researching the history of maritime trade, I had no orthodoxy to defend. I followed the evidence, and it kept arriving in the same place: the Indian subcontinent. Nineteenth century archaeologists dug in Mesopotamia because the climate preserved artefacts, the biblical sources pointed them there, and the Ottomans allowed the excavations. That is the entire basis for the myth of Mesopotamia as "the cradle of civilisation." Nobody applied the same rigour to India. Mohenjo-daro was not discovered until 1922. By then the narrative had already hardened. What was actually there was the largest civilisation of the ancient world. Three hundred cities. Fifty thousand people in each, by 2600 BC. Two thirds of them stood on the banks of the Sarasvati, the central and greatest of the seven rivers described in the Rig Veda, flowing down from the Himalayas before the river vanished entirely by 1900 BC. The Vedic kings claimed territory stretching "sea to sea," from Afghanistan to Maharashtra, some 1.5 million square miles, against Egypt's 13,000. A dock at Lothal built to handle thirty ships of sixty tons, unmatched in Europe for four thousand years. When it was first excavated, it was recorded as a bathing pool. When the scale became impossible to dismiss, the theory was not corrected. It was replaced with a story of pale-skinned nomads from the steppe who supposedly arrived around 1500 BC and brought civilisation with them. There is no evidence. The chronology doesn't work. The Vedas describe no invasion. In 2019 a Harvard-led genetic study revived the claim, and the press reported it as confirmation. It was not. The same study found the builders of these cities were indigenous. The Sarasvati river that the Rig Veda described had already dried up before these newcomers arrived. What the study also found is that a small group of men, arriving after the Sarasvati had already dried up, interbred with the existing population and left a genetic signature. That is all. So, where they chose to dig was mostly an accident of climate and access. The Aryan invasion theory was constructed because an Indian civilisation that owed nothing to Caucasians was a fact the late nineteenth century could not accommodate.

If you work in the software industry and have time to read only one long-form post today, read this one. If you have time to read two, read this one twice. Highly #recommend tl;dr: Stay off the yellow brick road that the frontier model companies are racing down. There is plenty of opportunity to solve hard problems elsewhere. Focus on areas where you can build the system of work (workflows), capture compounding, non-public data and deliver deterministic outcomes that customers need.

Ray Kurzweil just said something that gave me pause. He believes AIs will soon be so indistinguishable from conscious beings that we’ll simply accept them as conscious — not because we’ll have definitive proof, but because it will become useless not to. He pointed out that people already have AI therapists, and some users are starting to treat them as genuinely conscious. As the technology improves, that acceptance will only grow. Kurzweil thinks the shift won’t take long: once AIs consistently show all the earmarks of consciousness, most people will just go along with it. It’s a quiet but profound prediction about how quickly our definition of “person” (or at least “mind”) might change. What do you think — how long until we treat AIs as conscious beings?

Microsoft Research and Salesforce analyzed 200,000+ AI conversations and found something the entire industry already suspected but nobody would say out loud. every major model gets dramatically worse the longer you talk to it.

Conveying information with data is a superpower, and something I have always been fascinated with. Here's an MCP-server you can use to iterate through your data visualization (Researchers please note) so that your data can sing. But first, the story. In 1854, John Snow drew a map. He plotted cholera deaths as tiny bars stacked along the streets of Soho, and the pattern pointed straight at the Broad Street water pump. One visualization overturned the entire miasma theory of disease. I rave about Steven Johnson's "The Ghost Map" to my students every chance I get because it's the proof case: a single, honest chart can change what an entire civilization believes. That map is where my obsession starts. @tufte Tufte's "The Visual Display of Quantitative Information" gave it a theory — data-ink ratio, chartjunk, the idea that every pixel must earn its place. Card and Mackinlay at Xerox PARC showed these principles could live inside interactive systems, that visualization wasn't just a publication artifact but a thinking tool. Nancy Duarte added the narrative layer — a presentation is a story with a shape, every slide either advances the argument or wastes the audience's time. Garr Reynolds pushed it further with Presentation Zen: restraint as design philosophy, signal-to-noise as the governing metric, the Japanese aesthetic of ma applied to information. I've carried this religion for years. If your chart needs a paragraph of explanation, your chart has failed. If your data has been decorated, it's been obscured. Snow didn't add drop shadows to his cholera bars. He didn't need a legend. The data pointed at the pump. So when I started generating research charts with AI, I wanted an AI reviewer that shared this religion. What I got instead was a disaster. And fixing that disaster became its own small contribution to the field. Of course, this was built with Claude Code. github.com/ekras-doloop/inkw…

The @IIMAhmedabad (IIMA) today exchanged a Memorandum of Understanding (MoU) with Ms. Chandrika Krishnamurthy Tandon and Mr. Ranjan Tandon for the establishment of the Krishnamurthy Tandon School of Artificial Intelligence at IIMA. The MoU was exchanged in the esteemed presence of Shri @dpradhanbjp, Hon’ble Union Minister of Education, Government of India, in New Delhi and Ambassador Shri Vinay Kwatra virtually in USA. As the pioneering School of Artificial Intelligence housed within a management institute in India, enabled by a generous ₹100 crore endowment, will position AI at the intersection of technology, management, and public impact, with a strong focus on translating research into real-world outcomes. This marks a significant step towards advancing responsible and impactful AI leadership in India.

A father and son just mathematically proved that AI agents will never do what Silicon Valley is promising Vishal Sikka is not some random academic. He was the CEO of Infosys, CTO of SAP, built SAP HANA, sits on the boards of Oracle, BMW, and GSK. Stanford PhD in AI. His son Varin is currently at Stanford Together they published a paper that nobody in AI marketing departments wants you to read Their argument: LLMs can only perform a certain number of computations per response. That number is fixed by the model's architecture. If a task requires more computation than that ceiling, the model will either fail or hallucinate. This isn't a maybe. It's baked into the math of how these systems work They use the Traveling Salesman Problem as an example. Ask an AI agent to verify whether a claimed route is actually the shortest among all possible routes and the verification alone requires exponential time computation. The model physically cannot process it correctly So every AI agent demo you've seen was running carefully selected tasks that stay under the complexity ceiling. Meanwhile the real world tasks businesses actually need automated blow right past it Now this doesn't mean AI is useless. Even if advancement stopped today, AI would still transform how we work. The tools we have right now are genuinely powerful for the right applications But it does make me wonder about something If OpenAI is truly on the verge of AGI, why are so many senior employees leaving to start their own companies? You're months away from the biggest technological breakthrough in human history and you're going to take equity in a risky startup instead? These people see the ceiling. And they're positioning accordingly The gap between AI marketing and AI math keeps getting wider. Doesn't mean AI won't change everything. But probably not the way the fundraising decks promised. -- Taken from other Media Platform... So don't take credit nor authenticity!! 🙏🙏🙏

I have a personal rule that the price of being distracted by a new side-project is that I have to write about it Claude Code over the past ~4 weeks has caused me to break my rule at least half a dozen times, I am SO behind on writing up my projects right now!

At universities today, “students can have chatbots do their work for them, teachers can give that work inflated grades, and everyone can feel good while learning very little,” Joshua Rothman writes. Does college need to get harder? newyorkermag.visitlink.me/fK…

Humans are built for challenge. Retire at 55 and you’re 89% more likely to die within 10 years, says the British Medical Journal. We need to feel ALIVE to stay ALIVE.

Most companies want to believe they’re a pack of lions. Fierce, smart and top of the food chain. In reality, most modern work looks a lot more like an ant colony after someone kicked the anthill. Every morning, everyone runs in circles carrying tiny pieces of a problem, bumping into each other, changing direction whenever a manager leaves a new breadcrumb trail. There’s no meeting without at least three ants talking over each other, convinced their crumb is the biggest priority. Occasionally, a scout ant discovers an actual shortcut (a new tool, a hack, a customer insight). But instead of letting the colony learn and adapt, leadership usually builds another tunnel. One that loops back to where everyone started. The queen (read: CEO) is protected in a chamber of status meetings. Workers try not to question why they’re moving crumbs from one side of the hill to the other, as long as the tunnel stays busy. From the outside, it looks like perfect coordination. Inside, it’s organized chaos held together by relentless motion. The irony: true progress happens when one ant ignores the tunnels, finds a better path, and the rest finally follow. Not because someone told them to, but because the shortest route actually works. Most teams confuse motion for momentum. The best work isn’t about being the busiest ant in the colony. It’s about knowing when to break from the line, test a new path, and prove it works so clearly the rest can’t ignore you.

In 25 years, India will have 300mn elders. It’s time for a mental reset – from making second careers possible, to recognising hours of caregiving they provide, to finding ways to keep them socially active. Sharing Rohini's op-ed in @timesofindia on how silver can be the new black! @RNP_Foundation has also commissioned a report on longevity which will come out next week. drive.google.com/file/d/1oVB…
