Not likely in the near term...  Maybe in 5000 years or so, but by then I 
suspect computing as we know it will be ancient history (actually it *would* be)...

That's a LOT of zeroes.  Maybe my initial estimate was off by several dozen 
orders of magnitude...

LMAO!  I got a good laugh out of this one.  Thanks, I needed that...
