An upgrade to (say) a Texas Instruments Inspire or whatever the newest TI calculator is (in my day we used an 83 or 84) only changes the display of the data; after all, you input that data will old fashioned buttons as well. The calculator isn’t doing any magic with the data itself in order to display that. If you want nicely formatted fractions, square roots, or matrices, go to WolframAlpha and type in your expression in ascii; you’ll see nicely formatted output.

Heck, we have a bit of this already, when you consider things like Xcode’s image literals. Said literals can also illustrate some of the dangers of going too far with fanciness in the text editor, as anyone can attest who’s named a graphic “info” and then had it auto-complete every time they wrote a closure containing the “in” keyword followed by a carriage return.
