Oh, that's just tedious pessimism.  We just need processors that figure
out what we're going to ask them to do before we ask them to do it so
they can get a head start.  So if we program a really big AI computer
and train it to anticipate what I'm going to type and preload my
finished product before I start typing, we can beat that pesky old
limit.
