Of course. The question is /whether/ a particular feature is
adaptive, cognitive capacities included. You thought it would be
strange not to exploit the capabilities of neural ensembles. There
are lots of potential capabilities that just aren't adaptive in the
living world, like doing matrix algebra on the fly or modeling
four-dimensional hypercubes. That's what I was pointing out.
