Disruption, seen thru the users eye, by decade.
1980's: A phone was in your house.
1990's: A phone was in your house and in your car
2000's: A phone was in your house and your pocket
2010's: You have a computer in your pocket that you can make calls on.
2015's: What's a house phone?
Parallels to today?
Today's cars are like a phone in your home (been around for generations)
Self-driving cars are like upgrading to a cellular phone in your car (it changed everything)
Robotic Self-driving cars are a smart phone is to a landline. (the same, but, two completely different UX's... and a LOT more money too!)
How long will it take? Not sure. It took 5 years for Apple's iPhone to kill BlackBerry. If I were to bet on it, I'd see today's product engineering wizards and the billions$$ to be made and all the players aiming at the same target... I'm taking the under bet.
