???!!  TV's have changed dramatically in the last thirty years.  Not the
picture format, which is fixed by law, but the image clarity and relyability
is far better.  That of course ignores the fact that current TV's are about
to be phased out for digital HDTV's (at least in the states).

Medical gains are also accelerating, not declining.  Infectious deseases
unfortunatly are also ready for a comback.

Virtually all major feilds from industrial architecture, computers,
industrial manufacture, chemistry, aviation, farming, have all seen dramatic
improvements.  Theses improvements don't always do something obvious, but
they are there.

If the less intelegent can't find any job left at their skill level (or
atleast not enough for all), they will eiather have to improve their
abilities, or expect to be droped out of society.  Sooner or later people get
feed up with others living off them for no good reason.  

As for us and super intelegent AI's.  Eiather we'll find something to do
together (or co-evolve), or they will move on and ignore us. (We can hardly
expect them to take care of us forever.)

Its Cray not Gray.

Best current bet is that the human brain has E10 Neurons and can process the
equivelent of E14 bits per second.  Rough guess at computing power 1 teraflop
(one trillion floating point calculations per secound).  

The biggest computer I know of personally is a 4-5 tera byte (E12 byte
system) being constructed in my old neighborhood in Reston Virgina for the
phone companies cable TV experement.  The Cray corporation is building a 9
teraflop system for the US government DARPA research agency (completion
scheduled for 1998), and their competitor (thinking machines) is offering a 2
teraflop system comercially for $100 million. 

So we already are building systems bigger and more powerfull than the human
brain, we just don't really know how to make them think.  True intelegence
may require custom circutry.  But that circutry could be built in a way
similar to the current circuts.  If of course it does need couston circuts,
which is hotly debated.
