This is what I find amusing, we're in tech, how can you ask that? We've been rubbing stones to start fire too, but if you stick to that and refuse to use electricity, that's self-harming because you lose out on all the benefits.

You can't keep doing things the same way, that's now how technology as an industry works, the whole point is to come up with newer and better things. If you're a user of technology, then you can think like that and keep using old tech until the natural balance of things forces you.

I fully expect LLMs to be obsolete in a few decades, and I'm now wondering if people then will say how LLMs have been serving them fine for a few decades.

"just fine" isn't good enough in tech, "better" is always the goal.
