I have a few suggestions:

1. Better education. Don’t scare people who’re learning programming away from the lower-level stuff, especially as people are even getting scared to use type declarations, not just the pointers (of which I was fearmongered with in college, as they told me Java is the future).
2. Better portable APIs. Thanks to WebAssembly, one could easily have both something portable in a web browser and as a native desktop app, except instead we get browsers running said applications. I had some thinking about such a project, but then I remembered my iota project (a D-native replacement of SDL/SFML/GLFW, but without bloat by including standard library features), and then stopped thinking about it immediately, since a much smaller project already causes me too much headache. (Someone has a handy guide on win32 API? I have issues on getting certain messages produced, like input language change, and I don’t know if I glimpsed over some functions that enable them and just weren’t included in the documentation of the input language change event codes.)
