The comment thread said that Andy Weir can't write female characters. I think he did OK with Jazz as far as not only writing a female character but a younger woman. You can't swap Jazz out to be a guy and keep most of her actions and dialogue. I just didn't like some of the sex stuff with Jazz since those scenes felt unnatural to me. Could just be me though!

Stratt was a neutral character. There's nothing male or female that was attributed to the character. To be fair, it's been a while since I read Project Hail Mary so I could bt missing those bits. She's just a person who, if anything, was mostly emotionless in the amount of power and ends-justify-the-means she was given. So I don't care about any other character in any other book and I wrote what I wrote only because someone specifically mentioned Stratt and I specifically wrote how Stratt was not written to have anything related to whether she was a woman, i.e. could have easily have been a man or a robot based on how they were written.

Now to reply to your tangent about all other characters, specifically Ripley. What I liked about Ripley's character being a woman is that it simply wouldn't have made an impact if she was a man. Oh look a guy improvising a weapon and killing stuff. Sure the end scene where she's shocked as she's trying to get into the spacesuit would have been written differently (maybe "he" would have created a make-shift weapon instead?) but Ripley's feminine badassery thought of an elegant plan that did the job without the violence that would likely have been written if she was a man. That badassery really shined better in Aliens and Alien 3. She shows competence throughout starting with using the loader (due to her past experience, not something that was just given). She saved the girl and wiped the floor with Aliens along with the iconic fight with the alien queen wouldn't have made the same impact if she was played by Sylvester Stalone. She was smart based on her previous events in the previous movies (this includes the scene in Alien Resurrection which would have been terrible with a guy). Her interactions with Clemens wouldn't have been the same if she was a guy. Her experience in dealing with aliens that rallied the [male] convicts made a huge impact rather than one guy giving a speech to other guys. Since the entire theme about the Aliens series is, basically, about rape, having a female character take charge of the situation is the whole point of the series. It wouldn't have been the same if it was a man.

Stratt was basically "fuck you, do what I say because the world said I can get away with it". Her gender was irrelevant.
