Many years ago I worked as a geologist and watched as a very low-yield gold mine went thru cycles of getting funded, building some infrastructure and then declaring bankruptcy, until finally there was enough infrastructure there to actually make something happen (and maybe the rising gold price helped in the end).
It seems this strategy can be applied in different scenarios/fields and with money, people, money and people... Opens your eyes.
Sprint deployment / critical fixes are one thing, but for a year I did 90+ hour work weeks on a CPG startup and fried myself. More specifically, I was so burnt out on the very thing that was supposed to catapult me to the next level. The concept of positive burnout is very real..
I think success, even greatness is possible with a more manageable work/life/sleep balance. It's just far slower and more expensive. SpaceX and Tesla are brute forcing greatness at the expense of a few people that are also impatient for change/success. If they are on-board with the mission, they are probably okay with it until they get their gold and can rest (if they last that long).
