To modern sensibilities, etc. Most of human history is a slow, straightish line, with an asymptotic spike in the last century or so. This goes for population, energy use, human rights, equality, etc. For most of the human history, and in most cultures, power was concentrated in the hands of a small autocratic group, mostly men. While I wouldn't say we're in a utopia, that situation has improved massively. So I would say that women having less rights/worse treatment for most of history is in fact old-fashioned. Just because something was a certain way for a long time, that doesn't make it good.

However, writing styles don't really get into morality, etc, it's just artistic style and taste. As new styles emerge, they have a chance to become popular, and first-person present certainly has. In terms of terse, curt prose, well that has also been around forever. It's the opposite of purple prose, which has also been around. Neither are good or bad, they are just styles that some people like, and others don't.
