Irrational fear of technology is just that: Irrational.
There's nothing truthfully wrong with an implant or a device that can transfer knowledge or abilities between users.

However a fear of such a thing is not irrational in the society in which we live, where almost everything is controlled by sociopathic capitalists who only have their own interests in mind.
To give them direct access into your brain potentially is like going to a FBI building and trying to buy a child-sex slave. You'd have to be fucking bonkers to do that.
