"Moore's law" is definitely fading fast. But a "pseudo-moore's law" dealing only with performance, has a hope for quite a bit longer, but in the realm of parallel programming. N cpus on a chip has been done already. SMT is a different take on the same thing. A single chip with N cpus and M threads makes complete sense, although that will only extend the limit a few years, because you can't keep adding cpus without making the cpu die size requirement smaller. And that is what is coming to an end...
