It was 30 years ago when Terminator 2 (T2) came out. I vividly remember watching it in the movie theatre when it debuted, and I re-watched it over this past Memorial Day weekend. The premise of the film series is that civilization will be eliminated by futuristic machines uprising, and in the T2 sequel, Skynet, the 21st century supercomputer, sends a second terminator—the T1000. This one is more stealthy and more advanced, capable of rapid shape shifting and near-perfect mimicry.1
