and everything else is still speculation

Sure, nobody knows the exact future. But you still plan for what's probably going to happen. I don't know if social security is going to be around when I retire, and all the experts are saying it's probably not going to be. So, I'm planning a retirement without. Similarly, all the experts are saying AI (<- that word is not "LLM") is probably going to improve. I personally think it's irrational to ignore experts.
