The middle ground you're ignoring (between #yolo startup culture and Boeing's defense contractor culture) has been done pretty well with SpaceX's Falcon 9.
But are being worked on. This statement would've been true about landing Falcon 9 stages less than a decade ago.
> The sort of people that advocate otherwise have killed innocent civilians deep in the North Atlantic and are failing to run a previous healthy, if unspectacular, social network.
The differences between SpaceX's approach to safety and how Twitter's being run are pretty stark. Same guy, very different cultures. SpaceX's safety record is good enough for NASA, and they're hardly the #yolo set.
I respect SpaceX, but I also respect the real challenges of responsibly sending a crew to Mars.
