What if

 

 

What if my self-propelled electric lawnmower didn’t have a big handle to push it with, but had a controller box with a joystick instead?  Why are we walking back and forth across the yard with something that is already providing its own propulsion?  Is it because nobody has figured out how to steer something, or switch it from forward to reverse, without being in it, on it, or next to it?  I don’t think so.  Why aren’t we all in lounge chairs driving the mower with a remote-control stick?  Or why can’t a lawnmower learn our yard like a Roomba learns our living room and just mow by itself?  “Honey, I’m going to go mow the lawn.  Oh, nevermind, the Yardba already got it.”
