Sure. But bit by bit it is something we are doing anyway. All the
hardware now has to be dragged out of the bag, briefcase, pocket and is
very primitive. This is changing. Many expect humans to be online (at
least white collar humans) pretty much continuously by 2009. The
wearable revolution is a precursor to the next step.
The AI is at least as technically demanding. Neurosurgery is one path.
We have a few steps to take before we get that far. By the time we do
medical nanotech (or something close) will help. Over time we will
integrate human brain / computational resources more and more
symbiotically. It is an inevitable evolutionary step.
I would also point out that making humans smarter may well be necessary
in order for us to be capable of making a fully functioning AI (or seed
of one).

Augmentation will have made a great deal of headway at least including
fairly direct brain/computer interfaces which in principle opens up
quite a bit of synergistic/symbiotic potential. I would be very
surprised if enhanced memory modules that are implantable and auxilliary
logic processors were not available.

Actually I am assuming the uploaders will be more compatible and
friendly. I am actually of the mind that we will not get full AI until
humans are significantly more augumented. This is largely because I am
not sure we are bright enough and cooperative with one another to do the
job, because full AI may require a decade or two of hardware advances,
and because it requires significant theoretical advances as well as a
lot deeper thinking about implications and outcomes.
It is the AIs that will be playing a lot of catch up from both a
computational complexity of their "brain" and evolution trained set of
algorithms for action and understanding in/of the material world. We
don't even know yet that the human level AI can be built in less than
two to three decades. We know we can variously augment humans and that
there is great economic and creative advantage to doing so. The
augmentation may be small or larger. That we will have to see.

No. It is useful as a submodule and resource of real AI. And it is
certainly useful to us also. It is not a "failure". It is simply a
failure to produce full AI. But every path explored is also a success
if we learn from it and intelligently use what it did produce.
