Okay, let's talk about those connotations.
"Human" is a perfectly evocative word that does make people's "hearts sing". You have the "human touch", humanitarianism, treating things humanely. It reflects our highest aspirations for ourselves, and your rejection of it reflects upon you.
"Man" connotes... well, men. It depicts a society where the real movers and shakers are men. No one really hears "man" and thinks "men and women" (or "women and men" - why should men come first?). Notably, they say they do, but this has been shown by experiment to be inaccurate. If you say "man", people can't help but picture one. Indeed I also notice you use gendered language everywhere, not just in the word "man" to mean humanity. You say "men of letters", for instance, and you take care to match the pronouns. Am I really meant to imagine women when you write that? Would "people" not do just as well?
Lastly - far from being a "fad", this debate was active in the 70s, and has been entirely resolved now; nobody uses "man" this way anymore, and it sticks out like a sore thumb when you do. It sounds archaic to the point of comical. Consider if the subtextual message you want to send with your word choices is "I stubbornly refuse to adapt to the times".
Douglas Hofstadter (you may have heard of him!) wrote a lot about this in the 80s and 90s - I challenge anyone to read what he wrote and fail to be convinced:
