Scientists Make Biochem "Brain" From DNA Strands 63

thebchuckster writes "Scientists from the California Institute of Technology have created an artificial neural network (or a "tiny brain," in the words of the lead scientist) from DNA strands that interact with biochemical inputs. The artificial neurons of this network can take incomplete inputs, interact with each other, and come up with a complete conclusion. This is what the human brain does on a much more complex scale. It's also a principle scientists have used for computing and robotics."

    I always wondered if biomechanical stuff is actually better than "pure" mechanical stuff.
    Aren't the organic components less durable than inorganic ones by definition? If you had a robot (cyborg rather) whose organic brain expires, replacing the organic brain will keep the same functionality? Otherwise, will the metal/plastic parts work perfectly but the machine will remain an empty, useless shell?
    (Will patents and other tricks of "real life science" meddle on this? History dictates they will.)

    I don't know, maybe I am just a "metal purist", but I am not sure about having materials that can rot, into machines that might need to move in too-harsh enviroments or last long. I don't want such components to expire or rot because of one overheating (something a classic CPU can resist fine unless it's fire-inducing hot).
