Are Humans Still Evolving?

Every once in a while I will see a discussion about this topic, usually somewhat apocalyptic. On the one hand, we are indeed in a state where allele frequencies should be changing, so technically we are evolving. But it doesn't really matter what the current trends are--there is no way that evolution will have much of an effect within the next 200 years or so. And by that time at the latest we will have AI and genetic engineering that will render this discussion pointless. So, enough chit chat and fasten your seat belts already.
