Facebook could cure cancer with 1 line of code in website – computes.js

The title is insanely reductive. You could just as well say (assuming that cancer research funding is the issue with finding a cure--which is a highly debatable assumption) "The government could cure cancer by adding just two significant digits to this number (annual spending on cancer research)!"

In other words: the size of the light switch is not proportional to the illumination provided.

Also, those 80% of my computer's resources sitting idle are saving me battery hours and money off of my electrical bill, thank you very much.

This is garbage. Idle cycle computing won't cure cancer.
