Doesn't it kind of defeat the purpose, though?

If you have to train the AIs on every specialized new problem, and then you have to babysit them as you apply them to similar problems, why even bother?

It's not really intelligent in any real sense.

Automation can be useful and valuable (economically) even if not intelligent. Heck from a big picture view of solving a problem (say to manufacture something), then a solution/process/workflow etc that requires less intelligence may be the preferable one - if such a solution can be found, that is. It can be expected to be cheaper, more robust, repeatable.
