Earlier quoted context omitted.
I agree that this work ethic is indeed healthier and with most of the list, but I want to make one caveat: a programmer working secretly after hours to deliver more is not really a 10x programmer, he's just someone doing unpaid overtime (and risking burnout). Truly 10x developers also only work 9-to-5, the same as 1x. I also disagree that continuously improving is unnecessary. It absolutely should IMO. But it should…
Is that really a thing, secretly working more to give the appearance of higher output, while not even getting paid for it? Given the little time we have on this planet, this sounds like a suboptimal use of it.
In jobs where people have quotas it is very visible, seeing people scrambling to finish it all by the end of the month, to the detriment of their free time. But this is also the "secret" of some over-achievers.
It's absolutely unhealthy.
