Lemmy needs more content that isn't about US politics right now so I'm making a random post.
What's the most obscure cyberpunk movie you've seen? Name a cyberpunk movie you don't think anyone else has heard of.
I'm not saying you have to think it's a good movie (or that you even like it), I just want to discuss obscure, unknown cyberpunk movies. Come on, let's talk about something other than politics here.
So, this definition encompasses a lot of sci-fi, I think. For instance, the triviality of tech in Star Wars and the low life is definitely present, but it would be a struggle to vibe Star Wars with cyberpunk. You can make an argument that the stories in Star Wars is not about the tech, but as you do that you have away from the original definition.
I think this applies with a lot of "sci-fantasy" settings. Basic workers in 40k can acquire (or involuntarily be gifted) cybernetic implants and this does not change their social position. 40k is not cyberpunk. The stories largely do not focus on a critique of society through the expression of tech that would solve our particular problems. 40k mostly focuses on what would be cool for sword guy to do, and is largely viewed through the auspices of the top of society (players and great heroes).
An experience of a different setting that is definitely cyberpunk despite also being "sci-fantasy" is Shadowrun. People run around hacking mega-corporations computers by fighting their cyber-dragon firewall. But that also doesn't fit with my above experimental positions of cyberpunk, its much more an aesthetic choice for a heist game. Nothing wrong with that, but I think it hints towards cyberpunk being at least partly an aesthetic definition of cyberpunk.
That's not the say the thought is without merit. The focus of cyberpunk could be reflected in our own experience of, say, "having a device in our pocket that can trivially access all of human knowledge but I cannot use this to change my position in society". This is heavily reflected in Black Mirror. The plot that our protagonists have what would be a life changing device if you were the only one to have it, but are just coasting by (if that) is very cyberpunk and very Black Mirror.
I think one could play around with this concept quite a lot with TV shows, which tend to have a wider variety of focus, vibe, etc with the same initial concept. One could imagine a Doctor Who episode that fills a number of cyberpunk definitions, but Doctor Who does not vibe with cyberpunk generally.
