Was Moore's law, now something else, parallelism

You mean more modular and parallel than what?  They already support SMP (for
years since) and virtualization and hyperthreading...  How do you mean more
modular?

They still rule now.  Is there some alternative that doesn't use a
monolithic or modular kernel?  I don't know of any other option...

Now this one, I am completely missing.  How on earth can anything in user
space be *more* efficient than in kernel space?

I could see it, if you were saying "just as efficient" ... but "more"
efficient?
