You can make highly accurate predictions of what contrarians will say by assuming that they define AI as "whatever computers can't do yet."
LLMs aren't truly intelligent. [No True Scotsman fallacy...] They don't really reason. [A distinction asserted without giving a falsifiable definition of reasoning...] They're just next token predictors! [Which must be mutually exclusive with intelligence, I suppose?] Etc, etc, etc. Find your favorite pretext to dismiss modern AI, ignore the holes in the argument, and satisfyingly conclude that it's all smoke and mirrors.
Consequently you see hilarious takes from skeptics, like comparing today's enormous investment in AI to when people sold blockchain cartoon monkeys. Or claiming that modern models aren't useful for anything, as if they exist in an alternative reality where hundreds of million of people don't use them daily, and there's no incessant firehose of new tools/products/results discussed in news/social media constantly.
