Re: TechEd 2006 -- "parallelism is the new OO"

Andrew, you are right on, especially on complexity. I didn't see this till
now because I was busy with my new job teaching math in a community

Nevertheless I think it's what has to happen. I still think so, even
though thinking so has gotten me exiled from the computing world. There
are foundational problems (literally) with the metaphor-based languages
and OSs, and adding new features will palliate, not cure, them.

The further posts on the thread corroborate my point:

I wish we could get the attention of DARPA or someone... it ought to be
obvious even to a concurrency newbie that there is something horribly
wrong with this picture and the baggage it implies.
