The article forgets one thing, how DHH started his talk: he asked the audience how many people still codes by hand, and only 5 people raised their hands.

I was also waiting for some cool talk of some change, as I loved the simplificiation that Rails has done last year, but I also understand his point of view: he could either speed up the development of rails with AI (what Bun has done), or just say that it's mature and it doesn't matter anymore and it's better to not ruin a mature system.

There’s a Louis CK - yes I know, a horrible person, but unfortunately he used to be funny - joke where he asks the audience if they are in their 20s (loud cheer), 30s (less loud, but cheering) and in their 40s (very few cheers, mostly silent). The switcheroo is that he says “See, old people are smart! Why should they cheer? Who knows why I’m asking?”, or something along those lines. Well, it was funnier when he told it.

Anyway, the only logical conclusion clearly is that most Rails developers are over 40.

That was something of a public speaking trick, though. “How many of you are STILL doing X” is never likely to get many people to put up their hands. The speaker is framing it as stupid and backward.

People were afraid of cameras. You have to wear the AI Swastika in public.

I haven't been coding by hand for the last 15 years. The autocomplete of RubyMine is that good.
