It's fair enough to say "you can change the future", but sometimes you can't. You don't have the resources, and often, the will.
The internet was the future, we saw it, some didn't. Cryptocurrencies are the future, some see it, some don't. And using AI is the future too.
Are LLMs the endpoint? Obviously not. But they'll keep getting better, marginally, until there's a breakthrough, or a change, and they'll advance further.
But they won't be going away.
