My counterpoint is that "the internet" is quite recent, and has had many iterations - we've basically abandoned gopher, mostly irc, etc. Even "the web" as we know it is arguably entering a winter we can't yet foresee the duration of.
I 100% agree that "AI" is not going anywhere as long as humans are here (I wouldn't be building a company in the space otherwise).
I'm challenging this specific absolute certainty that "a swarm of agents building code like ants" will be living in eternal summer. This paradigm might be completely different just 6 months from now, from all we know!
