Ok so, TERMINATOR 2. wtf
so, in the time continuum, this war happens between the machines and people, and the machine send one back in time to kill Sarah Connor, who doesn’t die but T1 dies and pieces of the original Terminator stay behind - they fall into the hands of a tech company, cyber… Tech? Cyber whatever.
So BASED ON THE PARTS LEFT OVER BY THE TERMINATOR - that company develops a computer processing chip that later gets put into the machines that then revolt against the people.
predestination paradox
Nothing they did was going to change the future. It was all fate
