To be fair, all human desires have been manufactured by an external system: evolution.

We might imagine that we do what we please, in reality we're seeking pleasure/ reinforcement within a predetermined framework, yet most people won't complain when taking the first bite of a delicious, fattening dessert.

I dont understand evolution to be a sentient being though

I was thinking more Stanford students taking behavioral psych classes then going into the industry to help propagate ad driven platform capitalism

>So it follows that you yourself are okay having your own desires manufactured by external systems devised by other sentient beings.

This is nonsense. I already exist. I don't want my reward function changed. I'd suffer if someone was going to do that and going through the process. (I might be happy after, but the "me" of now would have been killed already).

A being which does not exist cannot want to not be made a certain way. There is nothing to violate. Nothing to be killed.
