@Tanuki I loved bashtop (100% shell) -> bpytop (Python) -> btop (C++):

@Tanuki These utilities are all small side projects for a single developer. Writing a modern shell is barely within reach, and fully replacing #GCC would require a huge investment, even if you start from #LLVM.
I heard that Google and Apple have pulled resources from #Clang a few years ago, and that's why #Cpp support seems to be falling behind GCC:
