Bullmore? Morebull?
If this article is actually based on something (which is questionable) it is likely on computer modeling of brain functions. Like most of our computer modeling it would be incomplete and so it's results would be as well. While the brain undoubtedly has some energy limits, there is absolutely nothing to say that we can't evolve higher energy and oxygen resources - in fact we already have compared to our more primitive ancestors. Given the state of the genetic research these resources could be increased in a rather short period of time - as in one generation to the next. Only really dumb people believe they can't smarter.
