Maybe, but so has Page—a self-driving car, a box where you can basically ask a question, the first major piece of wearable electronics after the watch—this aren't trivial. And yet, it doesn't impress me much more than Musk's existing achievements have—they're both in edison territory at the moment—brilliant businessmen—not Gutenberg, world-changing level yet.
Agreed, Google does a ton of things extremely well but the world would be more or less the same with subpar search or subpar youtube from some other company. If they can realize the self driving car or get everyone wearing glass then they've changed the world.
Tesla is on the forefront of getting the car industry to accept something they said couldn't be done. Battery powered cars. This will change the world, or maybe be required step for us to not wreck it.
