Well, let's say that tomorrow physics discovers a set of non-computable interactions called weirdodynamics, which can perform useful information-processing, and have the interesting property that any weirdodynamic interaction continues to interact forever. If a neuron can be demonstrated to use weirdodynamic interactions, and weirdoscanners used to find and retrieve a dead person's visual memories and display them onscreen, then I think any scientist would have to admit that there was a soul. Dunno about "non-material"; I've never heard a good explanation of what "non-material" could possibly mean.

I've seen the word "extropian" used in science fiction on three occasions: "Slant" by Greg Bear, "Voice of the Whirlwind" by Walter John Williams, and "Wang's Carpets" by Greg Egan. In the last two cases, the "Extropians" are a cult. In the first book, the "Extropians" are mentioned as justification by a member of a cult.
I have great difficulty visualizing, say, Anders Sandberg or Max More or Mitchell Porter as members of a cult, but I still agree with the SF in question. Once Extropianism goes mainstream, there won't be real Extropians any more; just Singularitarians and AIers and IAers and nanotechnologists... and one cult group, composed of all the clueless people, continuing to call themselves "Extropians".

The baby analog does show we can build intelligence, by doing the same thing as DNA (unless routine divine intervention is involved), but says nothing about whether we can create intelligence using only transistors, or whether neurons exploit weirdodynamic effects.
