My primary objection is not to the SIMT model, but NVidia reusing a term with an established meaning ("core") for something completely different and incomparable. Other companies terms like "execution units", "compute units" and "stream processors" (although perhaps not as much the last) are much more truthful about the nature of GPUs without hindering the programming model at all.

From the standpoint of a programmer who doesn't want to suffer through constant DIY chunking and packing (very close to my personal definition of hell), a CUDA core looks a lot like a CPU core. From the point of view of someone not writing the code, a CUDA core looks like merely another FPU.
