I think this is pretty much what most start-ups in the tech sector expect, it's similar to the over-optimisation problem in that because this technique has worked for some very successful companies then obviously every other tech-start up needs to overwork their employees and requires employees to dedicate their life to "the mission".
It's difficult because it's very infectious and it's extremely stressful to everyone who doesn't fit in with the expectations. I've had work experiences where I'm paired with very over-achieving engineers and managers might fall into the trap of comparisons: "Well he gets things many things done in a day and very quickly, why can't you also do that? We really want people to be motivated, to put in those extra hours if needed". And it's a difficult conversation because, how do you tell your boss you're not really interested in working those extra hours? That you don't really value productivity as much as they do, that well... that you have a life that you want to enjoy.
Building up unrealistic and unsustainable expectations is not okay. It's not okay to cry at work because of how stressful a deadline is. I mean, let's be honest here, this person was working at Stripe she's not a nurse that has someone's literal life in their hands. It's not okay to work 15 hours a day, our bodies and minds can only do so much.
And all of this for what? To "increase the internet's GDP"? Might as well just start a war while we're at it, that will for sure increase some countries GDP as well. Seriously, we are people not machines. It's good to be passionate, but where we put our passion is very important.
