>Terminals have no reason to continue to be used in my opinion. Note that this does not mean we shouldn’t use “textual” interfaces, quite the opposite: textual data is a bliss to manipulate. But we can very well manipulate text, along with other types of data, in something other than a terminal, that is faster, prettier, more powerful. (Graphical Emacs is one such example.)

I have recently switched to Jupyter's qtconsole for my REPL needs - for me, it hits the sweet spot of supporting rich media and interaction without the overhead of running a full web browser stack. I could see it becoming the basis for a next-gen terminal.
