What I love about Kasparov’s algorithm — “Weak human + machine + better process was superior to a strong computer alone and … superior to a strong human + machine + inferior process” — is that it suggests serious rewards accrue to those who figure out the best way to use thought-enhancing software. (Or rather, those who figure out a way that’s best for them; people always use tools in slightly different, idiosyncratic ways.) The process matters as much as the software itself. How often do you check it? When do you trust the help it’s offering, and when do you ignore it?
