In any case, we've gone from requiring supercomputers, to requiring very high end computers, to requiring $1600 video cards. It's tracking the exact same path that image rendering systems took (which if you haven't been keeping up there, now run excellently on pretty much any plain old computer), and we'll probably be there within a couple of years if not much sooner.
No normal person is spending 3-4k on a GPU from 3 years ago. The availability is also of questionable provenance.
Another nuance is that the computer hardware market is currently extremely inefficient in a way I don't understand. You can pick these cards up locally at places throughout Asia for around $2k new. That's retail single unit prices. No idea what's stopping somebody from closing the gap and making a ton of money - perhaps tariffs and data centers purchasing in a price insensitive fashion. Whatever the exact reason may be, what people pay for hardware is increasingly just radically different depending on where you buy it at.
I'm the guy who (Who plays games and runs molecular dynamics simulations and other CUDA stuff) said 3 years ago "$1600 for a graphics card? That is excessive. I'll upgrade in a few years when ready" And bought a 4080 for $1200 from Nvidia instead of the 4090. Oops! Now there is no reasonable upgrade path.
63% of Americans can't come up with $400 in an emergency.

The richest country in the world. Where all 50 states consume more than any other country in the world.

Can't come up with %25 of that in an emergency. (Even though the real price is something like 2-3x more than MSRP)
It must be nice, up there where you are so incredibly disconnected from reality.
