I suppose the difference is experiencing effort and getting the rewards associated with expending effort. You won't get that without wireheading if you outsource everything.

In my better moments, my identity resides in a tiny part of my brain, just observing different faculties doing their thing. In these moments it wouldn't matter if the work was outsourced. Then some scumbag faculty reminds me I'm a human and I should indentify with all kinds of processes I don't understand and suffer as a consequence.
