Right now Valve could disappear and gaming on Linux would continue, better for the efforts Valve have already made. I would think that the improvements would stagnate without Valve, though.
Non-Steam utilities like Lutris, Bottles and Heroic run games nearly as well as Steam. We’d carry on.
I work with a guy who suddenly developed this in the middle of a call. I had to help him back to the office, stopping so he could puke a couple times. He was gone for a while and I don’t think he ever got rid of it.
Sorry, I was mainly trying to say, “Good job, it’s impressive!” Your name is close to the name of a famous magician, so I was referring to your code as magic. Bit of a dumb joke.
