You do realize that what you just said was: GPUs are limited now to doing the hard stuff. CPUs still have all the low hanging fruit to exploit.
Its rather easy to add more cores and increase SIMD widths and CPU have the software ecosystems in place to quickly exploit the increased cores and increased SIMD widths.
