This is a bit silly.

There are just a few places where the most high tech hardware is made. If we turned off new and unregistered hardware now it would be just a few years as most hardware fast enough to run LLMs would disappear from public hands.

It will still exist, but be in the hands of militaries and authoritarian governments. If you piddle around on the net showing off your open standards you'll be relentlessly attacked by these entities digitally. More so, those areas will be generally embargoed.

The future looks like a new cold war with a lot more digital weapons.
