The next movie in the Saw franchise came out: it was the far future and the work of Jigsaw was now being some by nanobots, which lived in the bloodstreams of victims and formed small cutting instruments at preprogrammed times.
The ultimate goal of the nanobots was to create some kind of hybridized person. I don’t know the philosophy behind it. I do know that it resulted in dozens of people being held captive somehow, pairing off, and then having the nanobots essentially unzip them and carve them and disintegrate their bodies. Somehow they remained aware and cognizant.
I remember seeing tiny hacksaws emerge from their skin and begin cutting bloodlessly.
