Its not rocket science...
I think it's time we retired that phrase. Rocket science is older than computer science. And I actually think computer science is a more complex discipline that rocket science. Rocket science is essentially applied Newtonian physics. The achievements in computer science these days take a far more abstract mind with far more variables that rocketry. I'm not downplaying landing a rocket on a barge, it's an awesome achievement. But I think self driving cars for example are a far more complex science than landing a rocket.
Still think elons team are more than capable of both.
It's actually rocket engineering. Of course Green Pete implied that when he called it applied Newtonian physics. Indeed as he suggests, the science was done long ago.
