I agree, although LLM models are pretty impressive, we seem to be hitting some pretty serious limitations of that model.
I’m sure better models will be found, and we will probably have occasional technology leaps in the future as we have had in the past. I just doubt they will continue to accelerate as they have done historically.
Personally I’m a bit disappointed that we haven’t developed more since the 70’s. I thought computer based automation would be much faster and better, and standard working hours would have been about halved around year 2000.
So I’m not that impressed, despite there have been some cool developments. But things take time.

PS: In the 70’s fusion power was estimated by our physics teacher to be about 50 years away.
I remember it clearly, and I remember thinking as a teen, who the hell wants to work on something that will take 50 years?!
Now 50 years later, I’m not sure we are even half way there, and instead of cheap plentiful energy, we have climate change because we still use fossil fuels.

So again I’m not that impressed with where we are, compared to what I hoped and expected 50 years ago.
