Obviously, the technology would be incalculably dangerous. With d-mod, local nonsatiation goes right out the window, since you can instantly dial yourself to a “bliss point” where you are just perfectly satisfied and don’t want anything else. That’s the end of scarcity. When we can decide what we want, desire becomes less important than meta-desire. What do we want to want? D-mod is like putting the parameters of the utility function in the utility function itself. The resultant “clades” of humans will be very, very different from each other, much more different than people are now. This will make human interaction very weird.
