Tradeoff-busting solution of the day

 Prof Shiller:

Also, in the nineteenth century, the typewriter was invented. Of course, that may be the core idea of a computer. Your computer looks like a typewriter, but a typewriter just speeds recording of information. Tests show in the nineteenth century that people could type four or five times as fast as they could handwrite and there's no ambiguity because it's very clear what key was struck; whereas, handwritten--fast handwriting becomes impossible to read--or difficult.

Typewriter broke the tradeoff between the speed of writing and the speed/acuracy of subsequent reading.  The next stage: tradeoff between speech and typing ( voice recognition). And the next: voice expression and drawing vs speed of thinking.
