I think Dual Core CPUs are quite a different concept to SLI. With CPUs it's like this:
1) Constant improvements in chip manufacturing mean the number of transistors that can be put together at a decent price and decent size is always increasing.
2) These new transistors used to improved core performance by adding instructions to the CPU.
3) When they ran out of ideas of what instructions they could add they figured that using the extra transistors for a second core is more worthwhile.
Because of this Dualcore CPUs are in fact the same size and price as single cores used to be and they use the same amount of power. SLI on the other hand really is just "adding another one". Double size, double price, double power requirement. That's also why you can't even buy single core CPUs nowadays while SLI is used by less than 1% of computer users. The first post seems to hint at the idea that SLI started a parellelism trend that has brought us our Dualcore CPUs. Considering what I wrote above I don't think that's true at all.
