Meanwhile, our environment and the skills we need to survive in it are changing faster then we ever imagined. I would expect the human brain, which has done well by us so far, will continue to adapt to those changes.

We don't know what these new variants do. But they might confer a selective advantage by improving cognitive abilities. This needs to be confirmed.

We're envisioning what societies will want.

Our studies indicate that the trend that is the defining characteristic of human evolution -- the growth of brain size and complexity -- is likely still going on. If our species survives for another million years or so, I would imagine that the brain by then would show significant structural differences from the human brain of today.

We, including scientists, have considered ourselves as sort of the pinnacle of evolution.

The jury is still out on what this means because we aren't entirely sure what these genes do. It's possible they just control size and shape of the brain, rather than cognition. But the data is pretty compelling that the brain is evolving.
