The sheer rate of progress is what is meaningful. If LLM's agents were frozen now without any further improvement, your position would be must more defensible. But that's not what's happening, we are getting breakthroughs almost on a weekly basis.
Honestly, my gut feeling (worth every bit of what you are paying for it...) is that until we get actual intelligence instead of a good facsimile, we're not looking at an existential problem or a UBI-level problem, even, just a big change in tooling.
We are making steady progress. It’s not exponential per se like we used to see but in my experience models are steadily getting better. Also breakthroughs can be sudden.
