When the replacement of bash comes it will seem like a complete 'no-brainer'. In my opinion what should be happening is they should completely decouple the engineering from the interactive shell. The shell should just be a series of aliases and shorthands translating into something more robust.

But I also think they should move away from plain text for everything as well. Almost everything in a unix system could be better served with some kind of standard system of typing. Config files, program inputs (give universal tab completion) ... etc.

So I tried powershell and found it to be terrible. It seems like the implementation is killing the idea, stack traces all over the place - rather than helpful errors - and different types for file system objects (I cannot quite remember exactly what) making it hard to combine operations.
