Who Needs a Calculator, Anyway?

A rhetorical question, obviously. But check out this gentleman, who can calculate the 13th root of a 200-digit random number in his head, in just a little over a minute: http://www.smh.com.au/news/world/mathlete-works-out-200digit-number-in-head/2007/12/12/1197135500016.html.

Amazing! Not really all that useful, perhaps, but still amazing. . .

Best,

For this alternative to work, when one would need a calculator, apparently one would have to have access to an array of such focused, specialized, and well-trained people -- roughly one person ("button") for each major function available on the assembled crowd-powered calculator.

(I imagine a high probability of error -- not due to faults in any one computation, necessarily, but in the communication of intermediate results among "function processors" during chain calculations.)

And now you're describing the first computers. ;)
