Probably not, considering the brain is not layered and iterative like (non recursive/recurrent) neural nets are. The similarities generally stop after the resemblance between a perceptron and a neuron.
If THAT happens, then we can - after some further research - loose the last bits of our privacy - our mind...
Maybe one day. From my understanding we're not even close. We don't even have the computing power available to simulate a human brain. But yeah, scary applications. Minority Report anyone?
