Obviously, but the design change need not be perfect or even good, just a
little better than contemporaries who made no change at all. With a design
philosophy that mediocre it's no wonder that in just a few years, almost
certainly (much?) less than a century, we'll be able to make brains as good
as those that took nature 3 billion years to come up with, and then go far
beyond.
