You're confusing AI with OpenAI.
They, anthropic, others, are constantly pushing and over-extending, but theyve already long since by passed models that are useful for various tasks. Certainly not everything, but if the big players died tomorrow you could run a local model on a gaming GPU that would still do decent amounts of work if you were the kind of person who had a use for it.
Not everyone is, and thats ok.
I find chatgpt very useful for work, but id be cool with them failing and having to downgrade. Models already did what I needed well enough a year ago, maybe a bit more.
