Really what the title led me to believe was that bacterial colonies could be said to have some kind of intelligence, and I didn't see that in the video...
There are different ideas of what constitutes "intelligence" and "communication," I suppose. By the definitions I would use, there is definitely "communication" going on here (she refers to "talking in a chemical language," which is just a metaphor, I figure).
And, to me, information processing entails some kind of "intelligence" at some level. A computer may not be "intelligent," per se, but it can process info like a mofo. The "intelligence" comes from outside the computer, but, without it, there would be no information processing.
