I'd counter with: Natural selection in the classic sense ceases to have any meaning in an environment where all members of a species survive into adolescence, and reproduce.
Now natural selection is still occurring, but it may be leading to specization rather than intra-species evolution.

That just even more shifts the weight of human species selection machinery from r-selection (muliple, and thus more diverse, offsprinfgs, i.e. selection mainly by the best static fit) to K-selection - selection mainly by the best ability for behavioral adaptation. Ie. the natural selection, in the classical sense, is still there. It is the most important traits for defining best fit that are changing.
