As a kid, things like futuristic technology and robots were so cool to me for some reason. Things like Tony Stark's suits or just simple robots. Laser guns, the many classes of droids from Star Wars, super fast spaceships and flying cars. These things can range from the more well known things to the more obscure.
I say it was my autistic hyper-fixation that made me love these things that are still kinda prevalent to this day as a young adult (I’m on the spectrum). Only problem is that I can’t do these ideas justice with the skills I have. I can only imagine. Write them down. Actually, writing down the base ideas wouldn’t be so bad.
Nowadays I’ve gotten into things like DOOM and The Terminator as some of the more futuristic stuff. Just violent stuff ig.
