"That the automobile has practically reached the limit of its development is suggested by the fact that during the past year no improvements of a radical nature have been introduced."
- Scientific American, Jan 2, 1909
All of the things you mentioned seem like the kind of incremental improvements you get over an additional hundred years of iteration and improvement... but I think it is non-sensical to try to sell that refinement as as impressive as the burst of improvement and innovation you saw as cars were first being defined.
In practice, I think a lot of people want every individual thing we do to follow some kind of exponential or even linear growth curve, but it seems much more likely that everything follows a sigmoid curve: an S-shapes trajectory wherein after a period of slow improvements the actual meat of a particular innovation are really experienced during a much faster and almost explosive growth followed by a return to slow incremental improvements to wring out the last benefits (but never just becomes fully flat).
The reason why, on a whole, we see such great improvements in our lives is then because of the combination of numerous S curves from new paradigms that overtake the old and provide an illusion of smooth and continual progress.
Like, I do think the premise of "tech progress" slowing down is strange: in the past few years alone we've seen disruptive "radical" paradigm shifts occurring that have altered how people live their lives to a pretty radical extent--though if you wanted to discount anything that was catalyzed by political and medical crises I might be forced to cede my stance? like, looking back in 40 years, this might all look incremental as I guess a lot of it is still speculative--but banal things like word processors or even laptops, we're clearly pretty far past the growth phase of the S-curve, and so all the things we already have aren't really improving much anymore and likely never will.
Greed.
The stakeholders just want more.
Now that I think about it I’m not sure I’d put the change from gas to electric as more revolutionary than a number of these seemingly mundane improvements.
