Dunno what Eliezer would say, but here's my two cents:
Yes, it is unlikely that the greater part of humanity will ever upload. However, the extraordinary conpetitiveness of even fast human level intelligence (say, faster by a factor of 10) will mean that if a small percentage of transhumans intend to compete for the Earth's resources, some other transhumans and all humans will lose. IOW, upload or else.

The only technology required for that assumption is nanotech, and that seems to only be 5-20 years away. Curiously, the people most knowledgeable about nanotech predict the shortest times until we have it (e.g. Zyvex' website claims that they will have an assembler within 5-10 years). If so, and if the resulting machine is replicating, then posthumans could exist within weeks of that point.
