But that goes for each technology in it’s own time.

Which is why I specified a lot of technologies, and not all technology? We are certainly making some advances, but like I said it doesn’t seem to be at the pace we experienced in previous decades.

Take batteries. We have them for 160 years, and we thought they were a solved problem, but currently they make new jumps, and still ongoing

I don’t think anyone ever claimed batteries were a solved problem… We are making progress with them, but again, it’s been a pretty slow development over the last decade.

while smartphones are nearly solved

I don’t think I would make that claim either.

Therefore I say it’s his personal feelings that are having this certain cycle.

Or maybe you just lack perspective due to your age? Is there any particular technology that’s come out in the last 5-10 years that you consider groundbreaking? The only thing I can think of is LLM, and to be honest I’m not very impressed with them considering the societal cost.
