When WSL first came out, I realized that Windows might be Linux + Wine in 20 or 30 years.

Nowadays, with the Windows team barely able to produce a functional UI, what's happening with the NT kernel? Is it all graybeards back there? When they retire, the stability of Windows going to be in trouble, which is important for the things that really pull in the money. It'll get real bad, then they'll give up and move to an open source base, just like Edge.

The NT kernel continues to evolve. The recent examples I can think of are VBS, HCVI, and Kernel DMA Protection.

No reason to dump a very good kernel.

Why would you want to switch to in many cases, an inferior kernel? NTOS is the golden piece of Windows -- it's Win32 that's hot garbage.
