A flying car made its appearance about halfway through Tim Pawlenty's speech on the Fourth Industrial Revolution, in a short YouTube video of a German "electric jet" that looked a little like a Volkswagen Beetle with stubby wings instead of wheels.
This thing was clearly flying itself, and Pawlenty, in front of at least 200 suburban Chamber of Commerce members at the Edina Country Club recently, couldn't hide his enthusiasm.
"I live in Eagan," he said after the video concluded. "Think I'm driving down to Minneapolis when those are out?"
He wasn't trying to entertain a room full of chamber members with a gee-whiz gadget, by the way. He just wanted them to see how little still needs to be invented to make something like flying cars a reality. Self-driving cars that never leave the ground are operating right now.
So what will happen to the jobs of 8 million Americans now earning a living one way or another because people are still needed to drive cars?
Whether talking about 3-D printed houses or smart toilets is a shrewd way to win votes remains to be seen. Pawlenty as a candidate trying to reclaim his old job of governor will likely be as partisan as anybody else. But even if his political comeback fizzles, he will have made a contribution just by talking about these things.
The world has changed and will keep changing, he's been telling us. As much as people may wish otherwise, they will never be able to slow these changes down. And if they're feeling a little anxious about it, that's probably good. Now's a good time to start figuring out how to find a place in a changed world.
That point's not getting made nearly enough. In the race for governor, a race Pawlenty has entered except for actually saying so, one of the more curious developments so far is DFLer Erin Murphy unionizing her small staff of campaign workers.
