In other words, it requires a tremendous amount of effort to fully communicate your tastes to the AI. Not everybody wants to expend the time or mental effort doing this! (Once we have more direct brain/computer interfaces, this effort will go down, but I expect it will not be eliminated fully)

At some point, just an idea will be enough for your Neurolink to spawn an agent to create 1000 different versions of your idea along with things that mimic your tendencies. There will be no effort, only choice.
