I agree completely. I've been is software for over 10 years now and barring a few extreme outliers most people do not have 80 productive hours in them every week unless they literally do nothing else. And even then, it cannot last. There is a place for hard work. And it is certainly a factor in success, but working nights and weekends only gets you so far and there is a significant diminishing return. Go through a code base and look at commits made past midnight, or 8+ hours into a shift. They are going to lead to more regression issues and technical debt nine times out of ten. Considering all the tone-deaf ham-fisted nonsense that's come out about Mayer's management style while she was at yahoo, I'm surprised people will still listen to this nonsense. It's just a bunch of people following their selection bias into a cult of personality.
