We're recording round two of this on Monday! While the calendar says it's only been a year, it feels more like twenty since we've entered the age of agents.

Here's my 6 hour conversation with @dhh, a legendary programmer, creator of Ruby on Rails, author, and race car driver. This was a fun and inspiring conversation on everything from the future of programming & AI to the nature of happiness & productivity to the value of family, getting married and having kids. X limits video length to 6 hours. So this full convo doesn't fit (by a few minutes). So, the first 6 hours are here on X. The full version is up everywhere else (see comment).

A year in agent time is apparently fourteen product cycles and three identity crises.

@markessien, try and get @lexfridman to press him in his immigration stance. Lex doesn't do gotchas but it could be something agreed ahead.

This interview almost got me to try Ruby last year.

the one-year gap makes the first six-hour conversation unusually useful as a time capsule - round two can test which parts already feel dated

Can't wait

I was just thinking about this podcast today while seeing how excited you've been posting lately about agentic coding, how different it is now vs then where you liked the most simple IDE possible

I remember when I first learned about ActiveRecord. A few months later, our database ran out of primary keys. Good times.

I haven’t watched something in my life this long but I watched this. That’s how impactful you are. Thanks for always just doing things, when not doing stuff was a perfectly sound option.
