I skimmed it briefly and I think you have a lot of good material! I won't comment much on the writing itself, but I think you're pretty good. I wouldn't really call your writing "sexist" (it's a bit of an extreme word), although the first chapter for me had a lot of gendered cliches that hark back to mid-1900's "cult of domesticity" cultural values. It feels slightly anachronistic, given that your setting is supposed to be many centuries into the future, so I'd be curious if you had an explanation why Earth in the 2500's is like that. Your instructor's comment on the "names" -- for me, the name choices ("Bob" / "Lisa") feel a bit out of date/traditional, and even in the present day the popularity of these names are kind of dropping in the US. I see a lot more people in the older generation with those kinds of names than younger people, so it's just a slight oddity (at least to me). Lisa feels kind of like a throwaway character to move the plot along -- but she feels kind of artificial and fake -- probably because there isn't enough time spent building up the feelings. I think it would be nice to see more depth added to these kinds of side characters so they seem more believable and less cliche -- and not pulled straight out of TVtropes. I liked your second chapter a lot more and overall I think there's quite a bit of potential!
