Fast forward now to 2006 and things look very different.
We've not seen much improvement in processor speed
since 2003. Intel's Prescott chip turned out to be the
world's most expensive toaster. Hence the factor that
killed off the LMs is now out of play.

Moore's law continues unabated, i.e. transister count doubles every 18
months. And this is despite the problems major CPU manufacturers are
having pushing higher clock speeds.
The solution is multiple core architectures, which is now a trend.
Consider Sun's T1 chip which has 8 cores allowing the chip to execute
32 simultaneous threads. The next generation Sun chip is touted to
have 32 cores, possibly allowing 128 concurrent threads.

The hardware industry is now waiting for the software industry to catch
up.

In fact, one could argue that because single-threaded operation characterizes such a large percentage of today's applications, and because software has historically changed so slowly compared with hardware, then there's relatively little reason to push multiple cores per chip beyond *at most* a few dozen for the immediate future while continuing to devote significant concentration to improving single-thread performance too. ...
