I feel stupid not knowing, but I can't quite put my finger on where "See you space cowboy" is from. I know it's from an anime (that I think was made in the 90s?), but what anime specifically is it from?
I think it resembles a lot of Cowboy Bebop.
Cowboy Bebop (カウボーイビバップ Kaubōi Bibappu?) is a 1998 Japanese anime series developed by Sunrise. It featured a production team led by director Shinichirō Watanabe, screenwriter Keiko Nobumoto, character designer Toshihiro Kawamoto, mechanical designer Kimitoshi Yamane, and composer Yoko Kanno. The twenty-six episodes (sessions) of the series are set in the year 2071. It follows the adventures, misadventures and tragedies of a bounty hunter crew travelling on the Bebop, their starship. Cowboy Bebop explores philosophical concepts including existentialism, existential ennui, loneliness, and the past's influence.
