What of the people that look after the older ones? They need to feel what these people feel. At least it would help them to be better at care-giving.

PS: Staying eternal is not a bad idea though :p

I'm not sure about that. One's experiences can be misguided - you may think X is best for you, but acutally Z is way better. You don't necessarily need to experience something for yourself to give proper treatment - or medicine would be pretty pointless.

Well, that's the nature of emerging technology. This is just like saying that the creation of VR is pointless because it simulates a computer-generated imagery.
Or maybe; the flight simulation by student-pilots would be pointless; because you can achieve the same result with a real plane.

Hm. Haven't thought about it in this way. Seems at least reasonable.
