Doppelgangers

Yeah, I had seen this in the past - really have wanted to load it up and enjoy but ... all these other things to do - what I really need is a proper Doppelganger (didn't bother with the umlaut) - one that I can give instructions to - broadly speaking - and let it go and experience - and as its experiences happen they are duplicated/replicated into my consciousness as well.

And why just stop at one extra - why not a whole platoon of doppelgangers, all acting independently yet synchronously, with direction.

Interesting to contemplate how one would process the mass of overlapping and interacting thought/consciousness streams - both in real-time and with post-processing (dreams may come into play to assist here).

Needs some excellent sci-fi writer with a serious background in neuroscience and psychology to piece this all together!
