Is multi-core a given?

This blog was written by Stefanus Du Toit at RapidMind. He writes about the difference between SMP and multi-core. He concludes that multi-core is not a choice, but a given. Is he right? What do you think?

"That brings me to the fundamentally important difference between SMP and multi-core. SMP is a choice, that some applications chose to (and still choose to!) take advantage of. Multi-core is a given, that all applications must react to in order to continue to scale up performance."

He is absolutely right. Multicore is the most efficient way to scale performance above 1-2GHz once all the usual architectural techniques have been implemented (pipelining, caching, multi-threading etc.), so this is a given if software is to scale with performance. In fact software really need to be written for multicore to benefit from hardware multi-threading as well.
