Of course! It’s not like animals have jet engines!
Human brains are merely the proof that such energy efficiencies are possible for intelligence. It’s likely we can match or go far beyond that, probably not by emulating biology directly. (Though we certainly may use it as inspiration while we figure out the underlying principles.)
It’s to be expected. My theory is that millennials grew up late enough that they had access to the early Internet, so they got exposed to all kinds of strange cultures and had to learn tolerance and acceptance.
The younger generations grew up with an internet dominated by mega corporations, and algorithmic feeds. Unfortunately hostile states and other bad actors have been very effective at exploiting these mechanisms, causing a strong right wing shift simply due to exposure.
Your brain is strongly colored by what it consumes, of course.
