wrong. a cast vote for candidate 3 is not a lost vote for candidate B. Furthermore variable b decreasing doesn’t increase the total of variable t so no you can’t “rewrite” it like that with magic math. This is how it works, it’s actually very simple:
candidate T gets t votes
candidate B gets b votes
candidate X gets x votes
humans make humans, and humans speak human. Do we kill humans? The AI could also communicate just to dunk on us or attain some strategic advantage, you can’t assume any motivation really because an AGI would not have the same biological motives as an animal.
