Yes, you based it on something, but its still much of your work, you spend too much time on it, making, building, testing stuff. That is not easy job.
Whole T-1000 is built of nanotech as well. Problem is when it got freezed and scatter apart, it just can reassemble back to main mass. it seems that does not have core, that is also quesiton, how does it operate at all. yes,, in Genisys, T-1000 could split part of it, to spy on others. So it serves as camera or something like that. Blending into mirrors, floors, creating spikes to impale people, mimic other people is its tactical advantage, but still how does it operate is very questionable. T-3000 also posses all of those abilities, but not it's weaknesses. it can even regenerate. And can shortly teleport, when he was battling against Schwarzenegger. In fact, I think it is super speed or something. What is really confusing is that it consumes people's personality and memories, so T-3000 can behave like any human.
