Hopefully not too off-topic, I have a question: shouldn't we stop using terminal emulators already (i.e. why do we still require emulating the terminal hardware designed in 1970)? Wouldn't a text editor-like user interface be more sensible? (Perhaps, something similar to emacs' M-x shell but more universally adopted.)
