When I'm charged of not using the most cool and new technology, my 
favourite argument are the tombstones. They're made out of stone, which 
is a stone-age technology. But, as nothing more suitable has been found 
for that purpose, the stone-age technology survives. Up to now it turns 
out to be the most appropriate technology for that application.

The best course is always to pick up the most *appropriate* technology, 
as opposed to the one most *modern* or *fashionable*. There are 
applications where parallel computing is the best solution, and 
applications where parallel computing is useless.

My main line is on industrial process control. You must react in 
real-time to "events". A multi-threading approach, with threads 
activated by events, gives a performance which you can't achieve with 
any other technique. But if you attempt to apply our event-driven 
approach to optimize a matrix calculation you'll miserably fail.

Just my 2c
