good point, but to push back a bit, I think geopolitical factors such as Taiwan's Silicon Shield and the related AI arms race are as much responsible as free market principles for semiconductor improvements recently.
It's a good example of capitalism that kinda works right now - but, it could easily be the opposite... if China did takeover Taiwan, that company could easily (would likely very aggressively) do exactly all the late stage capitalism, death to innovation, money machine stuff that I've been describing - as almost/all other companies have done so with similar market positions.
tl;Dr: The only reason they are still making such good stuff is bc they needed/still need to be the silicon shield.
