Kind of surprised this is getting so much criticism. It’s a thought experiment, not a call for a fundamental change to all PC UX. My only real argument against the idea is that it’s framed as being “for efficiency”. If you want efficiency above all else you would just go full command line.
Helldivers 2 does the same thing. If this continues it will be extremely advisable to move any non-gaming use-cases to a different computer as you have no idea what the “anti-cheat” is doing with that level of authority over your computer.
