What happens when there are no more gas stations?

I picked up carpool from soccer practice the other day and told the boys that I had to stop to get gas.

After I was finished, I got in the car with them and said, "you guys will probably never do this with  your kids."

"Why?" one of them asked.

"Well, cars will all be electric or autonomous. In fact, you may not even own a car and you'll just summon one when you need transportation."

Then I said. "I wonder what will happen to all of the real estate tied up in gas stations?"

And one of the boys said, "and what about all the mechanics and people who work at gas stations? That's a lot of jobs that will be lost."

We all let that sink in for a moment.

"Yes, it will be," I said.
