One (late) 90's scifi work that touches a lot on transhumanism but is more depressing than cheery would be the exoplanetary Civilization video game by a philosophy major : ~~Sid Meier's~~ Brian Reynolds' Alpha Centauri : https://www.gog.com/en/game/sid_meiers_alpha_centauri https://www.gog.com/en/game/sid_meiers_alpha_centauri (And also the official game-derived books are downright depressing - though also non-canon.)
