E.Coli computers?

So I was checking out the news for the day and came across this article in Popular Science. Apparently scientists have learned how to reprogram a genetic circuit in the colony of bacteria.

" E. coli can do a lot more than wreak havoc within your digestive system. Scientists have made strides over the years turning the little microbe species into computational workhorses. Now a team of scientists at Missouri State Western University and Davidson University has devised a bacterial computer that can solve complex equations, using the bacteria as the brains.

Im not sure what to think about this to be honest....

Are the Computers of the future be bacterial based? If so... how long until the recreate the human brain?

Not the only questions that popped in my head while reading this but I wanted to know what everyone thought.

Enjoy

hate to be the barer of bad news, but this thread already exist here

Thanks for the head up... I attempted to do a search and could not locate any other threads about it....
