It strikes me as a virtual certainty that we will have massively cheap machine intelligence by then. And that's going to be, for better or worse, the most amazing thing that has ever happened on EartH.
In that case, we have a long ways to go, since most of our computers are about as powerful as worms. Good at different things, of course, but I don't see them helping too much. So don't wait up...well, I guess you should if you can, but that's a different matter. :)
Btw, never extrapolate trends too far! Technology can't surpass physical limits, which strongly seem to exist. So its growth should be logistic rather than exponential, and we're far enough away from the limits we know of that it makes sense we can't yet tell the two apart. -- JoshuaGrosse
