And the brain is better at writing songs,text, medical research...

In general, humans still beat machines at most mental tasks, except for ones which require monotony/speed.

My primary point is that the 'processing power' of the brain is estimated at somewhere between 10^15 and 10^19 flops. The lower bound has already been surpassed by supercomputers, but these computers are huge, orders or magnitude bigger and more power hungry than brains, so brains are more efficient. And yes, many algorithms run better on small numbers of fast processors, but the best known machine learning algorithms are massively parallel.
