The Alexa bit really shows that processing speed or "cheapness" doesn't always matter. The VM in AWS that eventually does that hex addition could have done 10^N

The Alexa bit really shows that processing speed or "cheapness" doesn't always matter. The VM in AWS that eventually does that hex addition could have done 10^N more of those same additions in the time it takes Alexa to hear the question and respond. But, humans are big and laggy, and I don't know if I could type in the question to Google or even a terminal faster than getting the answer from Alexa.
