This is a rather simplistic view of life IMHO. What’s wrong with people working for rent or groceries? What do you expect everyone to work on?

I think if you let your imagination wander and you end up seeing the scale of potential we have and what we could really achieve, stuff like paying for rent and groceries starts to feel archaic and wasteful, or as some kind of artificial constraint holding us back as a species.

Yes, so it's a good thing the first step is:

> [Step 1] Question every requirement. Each should come with the name of the person who made it. You should never accept that a requirement came from a department, such as from "the legal department" or "the safety department." You need to know the name of the real person who made that requirement. Then you should question it, no matter how smart that person is. Requirements from smart people are the most dangerous, because people are less likely to question them. Always do so, even if the requirement came from me. Then make the requirements less dumb.

Worth mentioning here that the SpaceX Falcon is the world's most reliable rocket, with a full success rate of 99.24% out of 394 total launches, 325 successful launches of the current version, and 98.5% successful booster landings of the current version, something no other orbital launch system even attempts.

At the moment, of course, two astronauts are stuck on ISS after Boeing's new spacecraft, developed along more traditional lines, experienced problems in its first crewed flight. They're awaiting rescue by SpaceX's Dragon, which has flown 16 times with crew and delivered astronauts to the ISS 10 times, all without a glitch. Both companies were awarded their crew contracts in 2014.

and nuclear reactors are incredibly reliable as well. do the ends always justify the means?

I firmly believe that iteration is the key to good engineering. SpaceX has got where they are (partly) due to running flight after flight with incremental improvements each time. The problem with the massive reactors is that you get to build only a couple of them, so you never get to take advantage of learnings to make the next one better/cheaper/quicker.

if you don't care about any externalities (like spacex), sure. but I doubt hospitals or just normal people who need electricity would be super happy about power sources failing because the people building them subscribed to the "move fast/break things" mentality instead of actually building reliable/safe infrastructure at the cost of it taking longer
