The hubris in tech comes in a variety of forms, but you've definitely hit on one of them. It meshes well with the view of humans you see from the self driving companies - "Humans process the world with a couple crappy cameras and some neural network stuff, we have HD cameras, how hard can it be?" Well, a decade or so later, "Really Hard" seems to be the answer.
There's also a consistent trend of "We know code, and are as like gods in the synthetic world of 99.95% reliable APIs and networks, therefore we can do anything we want in reality!" Reality, of course, disagrees, often entertainingly.
But these are the mentalities driving a lot of what runs our world, and it's quite frankly terrifying to watch in implementation.
