ROBOT CARS….Matt Yglesias, riffing off a Tim Lee piece, says that self-driving cars could free up lots of parking spaces. Which is true, I guess, but seems sort of like saying that cold fusion would be great because it would allow us to build smaller cooling towers. If we ever do build a genuinely self-driving car, it means we’re only a stone’s throw away from nearly human-level artificial intelligence. More efficient parking will be the least of our worries at that point.
