One thing the article mentioned was that people are choosing not to have kids. In this case, it seems that there should be an extremely high selection pressure for people to be genetically more predisposed to want kids. And if this does evolve to be the case, then as long as technology does not make reproduction free (in economic terms, there is currently a finite "supply" - the number of fertile women in the world times one baby per year), then competition on other traits will begin to be more relevant.

So while people are saying that evolution is "selecting for less intelligence", this may be a short-term effect in which we are first as a species shifting to stronger reproductive urges at the expense of general intelligence, and only then increasing intelligence in a way which doesn't allow philosophical objections to having children.

But evolution is pretty complicated, and difficult to reason about. Other people have also mentioned the "selfish gene" effect, in which altruistic / kinship behavior can be good for a gene, but suboptimal for an individual. It's possible some weird effect like that is going on also.
