I'd so have preferred this to be true, and to ignore the AI thing (mainly to avoid any effort to change any of my habits in any way). But as an end user I can say that this is wrong. I definitely need LLMs for one critical thing: search that works.
Google has become clogged with outright spam and endless layers of indirection (useless sites that point to things that point to things that point to things, never getting me to the information that actually fucking matters), but I can ask the best LLMs queries like "what's the abc that does xyz in the context of ijk" and get meaningful answers. It only works well when the subject has a lot of "coverage" (a lot of well-trodden ground, nothing cutting-edge) but that's 80% of what I need.
I still have to check that the LLM found a real needle in the haystack rather than making up a bullshit one. (Ironically, Google works great for that once you know what the candidate needle actually is—it just sucks at finding any needle, even a hallucinated one, in the first place.) For shortest path from question to answer, LLMs are state of the art right now. They're not only kicking Google's ass, they're the first major improvement in search since Google showed up 20+ years ago.
Therefore I think this author is high on his own fumes. It reminds me of the dotcom period: yeah there was endless stupid hype and cringey grifters and yeah there were excellent rants about how stupid and craven it all was—but the internet really did change everything in the end. The ranters were right about most of the battles but ended up wrong about the war, and in retrospect don't look smart at all.
