If Steam manages to make compatible most or all of it's gaming back catalogue with Linux over the coming years then there will be more emphasise on Linux gaming being a real thing. Hopefully with the popularity of gaming will come other more professional offerings like some stuff from adobe and others.
If this happens there will be more interest in superseding Linux. There are many kernel options. a feather kernel or micro kernel might replace over bloated systems. Why you could write in pseudo code and have the AI convert it into HTML 5 and WASM and and with evolution of WASM scrap the rest of the programming languages which instead could be formats accepted by the AI which then codes into the native OS machine.
This sort of standards unity could bode well for clo0ud service interoperability among platforms.
