Star Citizen itself is my answer... I remember reading an article in Popular Science about it [0] when I was a kid, and specifically the sentence about "For example, designers modeled each ship’s landing gear to retract without interfering with the hydrogen fuel system that feeds the nuclear reactor." That sounded like the coolest thing ever.
So, now that I've gotten eight years older but still haven't seen the game release, it makes me kinda sad.
Relatedly, another PopSci article [1] promised that flying cars would be available by ~2015. That never happened either :-(
LevelCap has done some great star citizen videos recently, just him and some friends playing the game. If you're interested in the current state check out his channel:
