AI will be a force amplifier. great, we get that. I suspect that this kind of vague marketing bollocks will be generated almost without any oversight soon.
However there are also risks. Just like calico which used to be a really expensive luxury, and then with empire and colonialism, and later mechanisation became a cheap(er) commodity, LLMs will kneecap whole industries.
I think any site that relies on advertising on the web is going to die. This includes google, as they are the gateway to the web, and rely on you using them to answer questions obliquely. This means that the need for web developers and support staff is going to decrease.
I think the open web will shrink to ~20% it's present size. It will mostly revert back to hobbyists and people arguing. Things that require up to date data will continue (news, sports, gaming, etc.)
Social media will either thrive, or revert to small group chats (think half whatsapp half tiktok/instagram), to get away from autogenerated horseshit.
As for streaming TV/movies. AI porn is the canary there. If that takes off, then your kardashians/court reality/low budget drama might feasibly be generated (we are a way off though)
