They only improve your life if you actually work on something that you yourself are trying to improve. Most people are fine with the status quo, so if something like LLMs can take over the understanding of complex tasks, they won't even notice, except for the fact that more of these tasks will get done.
There are clearly things to understand more than just the immediate stuff you do for work. I think most people are thirsty for understanding, it's just... many times it's in other domains than you expect.
