Humans are easily hackable by other humans all the time. We have very few safeguards in that regard, and even make a virtue out of being mind-hacked. Some examples: falling in love, being radicalized into participating in the Jan 6 riot, any movie scene where a character has an epiphany based on what someone else said and completely changes their behavior. This mundane manipulation of humans is pretty dramatic but unnoticeable from the inside the society. If the former president can do it to tens of millions within a very short time, surely something smarter can do it without humans ever noticing the sleight of… manipulator.
