I can't speak for Marissa, but I certainly did pull one or two 130-hour weeks "back in the day". They _were_ productive. I did pay a huge price for them, both in terms of reduced productivity for weeks afterwards, and in terms of health. (I always get a horrible cold after exhausting myself that much)
There are two things to keep in mind:
1) These weeks were rare. I'd expect they were rare for Marissa too. You can't do that anywhere close to regularly. And you don't. Those are heroic efforts to meet a particular deadline.
2) That was "back in the day". Late 20's, early 30's. As you get older, those efforts are much harder. (Damn it, all the old people I knew needed next to no sleep. Can I please finally be old enough for that? ;)
There _are_ deadlines that are worth it. Putting in the extra hours so the decision demo to the VC guys is smoother? Uh, yes. Same goes for e.g. working on reducing network traffic before a spike will hit, if that reduction will save you a million or two.
In all cases, make sure the payout is commensurate with your effort - i.e. unless you own equity or there is a large bonus attached to that, IMHO you should tell the powers that be to go pound sand.
And putting in those hours because your manager didn't listen to your estimates in the first place? Hell no.

Yeah, definitely agree. I was more referring to employee positions without significant equity, which you touched on in the rest of your post.
I don't doubt that they were productive. It's just that such long hours are frequently a way to cover up lack of productivity rather than increasing your productivity.
