On Windows, I can buy whatever mouse/keyboard/monitor/CPU/GPU/sound card/USB headphones/USB drive/etc. that I want, plug it into my PC, and it will work correctly 90% of the time. In fact, most of the time I won't even have to think about it. The other 10% of the time, I'll need to go to Windows Update (or, in very rare cases, the manufacturer's website) to get the driver... which will install itself completely automatically.

On Linux, I have to carefully research which hardware works and which doesn't; which config files I need to edit by hand; and -- if I'm feeling adventurous -- which kernel flags I need to unset to get it all to work. If I'm very lucky, my new hardware will work in some capacity; it will almost never be 100% functional, but maybe I can get it to the point where it's good enough.

This is a massive problem for everyone, but especially for gamers, who absolutely must have their GPU, monitor, audio, and network working correctly and at peak performance. This is also absolutely not a problem for ML developers, network admins, etc., who operate on clusters of 1,000 machines and couldn't care less about all of the peripherals. Guess what, though... there are way more regular users out there than AI network admins.
