A Medium article on driverless trucks went viral in my Facebook and Twitter feeds last week. It seemed as if everyone I knew was suddenly deeply worried that these robo-semis were going to hit America's economy like, well, a Mack truck.

I started to respond to those individuals, but wait -- I have a column! At least until Google introduces its Writerless Column feature next year.
