Kluger/Clever Hans? [1]

The funny thing is: the abilities that people thought of as clever at the time (doing maths) can be done with a $1 component these days. The thing Clever Hans actually did (reading the audience) is something we spend billions on, and in some circles it's still up for debate whether anything can do it.
