I personally think the alarm ringers are mainly the privileged elite who are scared of their moats beyond filled in. LLMs have effectively broken down the gates of access to knowledge. In a diverse world, having more people being empowered to do more things has to be a net positive.
Once people get over a few hurdles, things like: >tech's too confusing >$20 is a lot of money to spend on a subscription >AI is just a fancy search engine >AI will do all the work for me
You start unlocking a fair bit of creativity in people. I mean, all this is brand new stuff even for tech-savvy people. It'll take a while for the genuinely useful uses to dissipate out into the maasses.
Not everything has to be a billion dollar business.
