Abacus vs. Calculator

Nov 1946: In a contest of old vs. new technology, the abacus beat a calculator in a contest of speed in all categories (addition, subtraction, and division) except multiplication.

I’m assuming a modern computer should now be able to outperform an abacus, though I suppose it would depend on how quickly one can input the numbers.
