Yeah. Sometimes someone brilliant does something hard for the good of humanity though. I'm think specifically of that guy who wrote DXVK back in the mid 2010s. He basically made gaming on Linux possible.
He is certainly brilliant (I remember how quickly it went from showing a single triangle to actually having working games), but was quickly hired by Valve to work on it full-time.
Yeah, it was nuts. Us Linux gamers were all upset at CDProjekt Red for the bait and switch on the Linux support for Witcher 3, and then, blam DVXK suddenly made that irrelevant. And then so much more!
