Fish is nice and I eventually learned to accept the scripting. BUT if it is the shell for the ‘90s what is the 21st century shell?

Of course I think my own project, Oil, could be a "21st century shell", or I wouldn't be working on it :) It's designed in a principled way, and it's also the only one that's compatible with bash.
I'm not so sold on some of the tokenizing / etc styling, but `cat image.jpg` -> see an image? yes please.
Alternatively, I keep checking in on Xiki periodically, since it has some extremely interesting features: http://xiki.org/
