I agree if the code could be made open source (making the code available for the inspection of all) it would be good. But as stated in the video if it contains A.I., then most likely it will not be possible to open the source. The reason being as soon as the software goes online it will get upgraded by the software itself. And what happen with the A.I. in the facebook experiment will happen again. (ie. No human will be able to read it)
