CUDA on Windows Subsystem for Linux 2
Pity. CUDA was/is proof positive that Linux on the desktop is perfectly feasible and that you can use it to both do a UI and do meaningful computation on the same machine without getting tied down into all kinds of licensing schemes. Opening this further up to Windows gives fewer people a really good reason to try out Linux as their daily driver. I personally don't get why any developer would prefer Windows over Linux with its near infinite software repositories related to all things developers would like.
