Don't worry, there are a lot of drivers for investment in performance 
increases
in semiconductors and storage, and the phenomenon you worry about is already
pervasive.

You can apply more computational power to a problem in either or two ways:
you can get faster processors, or more processors. We are getting 
increasingly better
at distributed computing. Yes it's hard,a nd yes, it works better for 
some problems
than for others. But our canonical worked example for intelligence, the 
biological brain,
appears to be a massively distributed implementation.

For disk drives, we see exactly the "problem" you mention. Drives have 
quit doubling
in capacity, and instead are now dropping in price, specifically because 
a nominal 1-drive
system has "enough" capacity.  You should look at
   http://www.pricewatch.com
occasionally to get a feel for this trend. Disk capacity improvement 
have consistently
outpaced processors performance improvements for at least the last five 
years. The current
"sweet spot" for cost/GB is at about 250GB for $.50/GB, at retail.  Add 
$500 for a cheap
computer to house four drives: you get 1TB for $1000.

The only way I know to use this much disk at home is to store DVDs. 
Storing audio
CDs hardly counts: my entire CD collection fits on <<300GB with lossless 
compression.
You can store about 5 audio CDs with lossless compression (flac) in one 
GB, for a storage
cost of $.20/CD. Storage cost for a DVD would be about $4.00, which is a 
small fraction
the purchase price of a DVD. In my case I have a legal, physical CD for 
each of the CD images
on disk, but you can see why the RIAA and MPAA are panicking.

If the semiconductor manufacturers move off the performance curve, they 
will simply move
to the price curve instead. We will see retail computers at $100. With 
the semiconductor content
dropping in price each year. due to intense competition on margins. But 
this means that
the cost of building a cluster will drop dramatically, so the 
singularity continues to advance
at its inexorable pace.
