Oh yes, it's certainly possible -- but not within 10-20 years.

Ah, but introduce *how*? Drexler introduced it by writing a
nontechnical speculative book (Engines of Creation). It generated a
lot of popular buzz and a collective cold shoulder from the
scientific community. He then, much later, wrote a highly technical
book (Nanosystems). This produced much less popular reaction, but a
much warmer reception from scientists. One could argue that it is
Nanosystems that is largely responsible for nanotech finally becoming
the acceptable buzzword that it is today. (I'm not convinced that
Engines of Creation had any real benefit.)
It would be ideal if the same thing could be done with uploading:
someone with good neuroscience credentials might write a highly
technical book about uploading: theoretical arguments about why it
must be possible and plausible, detailed proposals about how it might
be accomplished.
(I started such a book when I was in grad school, but alas, it was
too much work to finish properly while keeping up with my research.
And since then, I have changed careers, and am no longer the right
person to write such a book anyway.)
In an environment lacking such a detailed, technical, and coherent
argument, we are going to have a hard time getting anyone to take us
seriously. (Though the recent NBIC report is highly encouraging.)

Well, me too, but I believe that it is. Researchers would love to
have detailed 3D maps at 10-nm resolution of all their favorite
organisms and tissues (e.g., retinal circuitry, leech ganglion,
Aplysia ganglion, etc.), but the only organism that has *ever* been
mapped out to that level is C. elegans -- a creature whose entire
body is less than 1 mm long, and that was a herculean effort that
took years of highly skilled labor.
Even today, the best computerized EM labs in the world (e.g. the
Ellisman lab at UCSD, where I studied for a couple of years) still
rely on highly skilled labor for ultramicrotoming and photography,
and in any particular sample, there is a huge amount of damage and
loss. The pictures you see in the journals are the good areas; pan
over a bit from any of those, and you'll find tears, holes, sections
fried by the electron beam, etc.
Add up the amount of labor it requires, even today, to image even a
small volume of tissue, and you'll see that it would take years to
scan in 1 mm^3 this way, even if you could ignore all the gaps in the
resulting data.
So, what's needed is a machine that can automate the
ultramicrotoming, as well as the microscopy. This requires
specialized MEMS -- not nanotech, thank goodness, but not the sort of
thing you can order in your lab supply catalog either. It requires
serious invention, and the early models will probably not be much
faster than human hands (if even that).
That's why I think scanning in 1 mm^3 is a good goal -- it will
probably still take 10-20 years, unless a benefactor decides to pour
many millions of dollars into it. But it's achievable, and once
we've gone that far, we'll be able to make much faster progress by
improving the size, speed, and quality of that machine.

I think even the uploading of a small creature is asking too much.
I'd suggest focussing on the structural scanning at this point;
uploading requires a solution of all the emulation issues too, which
is going to be couple career's worth of work after we have good
digital ultrastructure in hand.
However, a machine that can replicate the pioneering C. elegans
structural study, but in a few days rather than years, would be a
very good goal.

I don't think my picture is bleak. Futurists tend to make two
mistakes: they're too optimistic in the short run, and not optimistic
(or imaginative) enough in the long run. I think you're falling into
this common trap. It's easy to look at a problem, seeing the big
picture, and think a solution is right around the corner -- but in
reality, the problem is in the details, and they take years and years
to resolve one by one. Progress, on a close-up scale, is slow. It's
just when you step back and look at a sweep-of-history level that it
seems so fast.
Combine this general tendency for near-term progress to be slower
than you would expect, with the fact that virtually nobody is making
any concerted effort towards uploading technology, and you see why I
have made my cryonics arrangements (even though I'm only 31). Nobody
is working on those MEMS machines which can slice and ferret away and
image frozen neural tissue. There isn't a demand for it, nor is
there an easy way to explain to funding agencies or investors why it
is worth what it would cost to develop.
Please understand, I do believe it'll happen -- in fact, it is slowly
happening already, with every tiny advance in neuroscience and
related fields. But it's not rapid progress. Researchers spend
entire careers studying one small family of ion channels or whatnot.
That's just the way things go.

Prize money can't fund primary research. You have to pay grad
students and lab techs; you have to pay for equipment and reagents
and the building and electricity. No researcher would put any
serious time into work that isn't being funded directly with cold,
hard cash -- not the possibility of cash at some point in the future
if nobody else beats them to it first.
The way this could be made into primary research would be through a
granting organization. I don't know think you could yet convince any
to make such grants, though. And I don't think we have the resources
at the moment to start a new one.
What prize money can do is add a little extra interest to work
researchers are already doing, or get them to spend a little bit of
extra time on a side project directed towards the prize. That can
certainly be better than nothing.

Yes, if it were described not in terms of mind uploading but in terms
of the research it would enable, or other immediate results. Indeed,
that's probably how researchers who care about uploading are funding
their research now.

Heh -- that's like an 18th-century person saying, if we could build a
craft that goes to the moon, it would teach us revolutionary things
about how our horses relate to their carts. In other words, by the
time we are able to upload a rat, we'll be long past studying the
things you study with electrode arrays. (Indeed, without those
studies, I doubt you could solve the emulation problems that
uploading will require.)

OK. Let's reconvene this discussion in 5 years and see. :) It's
now been, what, 10 years since I first launched the Mind Uploading
Home Page, so I don't mind sticking around for another 5!
Best,
