Sorry for being off topic, but if you want real experience than use low dose of LSD with high dose of strong stimulant like meth or cocaine and watch porn (virtual reality or regular TV). That is much better technology than any "robotic" form that will come in an foreseeable future. Just my opinion. I have stopped using "sex tech" because they were damaging to my real life. I doubt I will use it in the future.
But for folks that are into it I think that breakthrough will come when technology like transcranial magnetic stimulation is merged with two way system "brain-porn console". It should be easily programmable and very light with no wires. Set the console, put wireless magnetic coil, close your eyes (or put the blinder) and enjoy visual and tactile world created inside your head. That should be intermediary step before star trek like hologram.
I believe technology exist already but is being used under the slogan "make war not sex", so we should not expect it before another big technological revolution inside the military complex. When it becomes obsolete for warfare, DARPA will give it to some "new ingenious company" that will patent it and make lot of money. Sorry for digression, but every single thing is much more complicated than we think. Or is more simple if one knows how the system works.
But, yeah ---> "Transcranial magnetic porn s(t)imulator" is my prediction.
P.S. If you are going conservative and using stimulants then coke should be administered in an continuous infusion because of short duration of action it has.
P. P. S. DISCLAIMER - Do not listen to me. Do not use LSD, meth, or cocaine. They are illegal and can lead to heart attack or stroke.
