Would be nice if there were some kind of open source, cross-platform, low-level graphics API, maybe overseen by some kind of pan-industry group (or "consortium" if you're feeling fancy). Just spitballing but you could call it "Cape" or "Hephaestos" or something.
Would be great too if there were one or two open-source, MIT- or dual-licensed game engines that target this API. Maybe even some runtimes so you could target PC and the big three console platforms.
In fact it would help game development as much as "similar" approach helps the web grow the way you don't need to reinvent the wheel every time. Although you can.
