I hope we can get to a point where we don't need to build tools and ecosystems around a single language. It seems there is just an explosion of domain and generic languages and I see that as a good thing. I want more tooling compatibility so that developers can pick and choose what works for them and maybe even mix them together better. Better educational tooling so we can pick them up faster, or read languages we don't understand easier. etc, etc. things like WebAssembly, LLVM/MLIR, python->jupyter notebooks give me hope.
