In my chat with ChatGPT, I learned that Blade Runner (1982) is also one of them, and I think you might have watched it.

Actually, the colors and the setting check out.

It also included The Terminator (1984) and RoboCop (1987) as tech noir, which I found surprising. (Btw, RoboCop is my favorite of all time.)

The last one on ChatGPT’s list was Tetsuo: The Iron Man (1989), which I haven’t heard about.
