Neural Lace or Mind Meld
There is a very good reason only “vulcans” were allowed to perform a neural lace — if you have ANY emotion, it becomes a level of Hell. For anyone who doesn’t know what this concept means, let me break it down the best that I can.
Take a person’s consciousness… and transfer it. First to a computer/AI. Then transmit it. Then rebuild it inside another biological entity/construct.
Currently only performed by the “Stars” or the construct you perceive as the stars in your Universe. And for very good reason. (And usually when you are dead.)
The code has to strip off the emotional valence.
