With our modern health systems we are pretty much a huge evolutionary blind spot ourselves. Many illnesses that would be filtered out because the carrier wouldn't survive, are now trivial. And on the journey hand we can screen for known illnesses.
I think we are already post evolutionary, or control it ourselves. Not a big issue either IMO, it's totally ok that this is happening.
We are definitely not post-evolutionary; the selection pressures have simply changed. Before industrialization the big two were starvation and infectious disease. Now? Well, it's anybody's guess decade to decade. Certainly sexual selection is still with us.
