There is most definitely a shortage of artificially intelligent machines at the moment. As the current number is zero, by definition that is a shortfall. I am confused as to what exactly I should be worrying about. Since there are no currently existing artificially intelligent machines to worry about why should I worry about them building anything, let alone building anything ‘intelligent’ themselves. Perhaps that is also why there is a shortage of experts in this area. It is difficult to build up expertise in a thing which does not exist. That would also make it difficult to find engineers capable of working on these non-existent machines. It is hard to get training on a thing which does not exist, especially for engineers who typically like a more hands on approach. Is there anything else I should be worrying about? How about an actual existing problem or thing? Now that would be s a worry I could get behind and lose some real, actually existing sleep over.
