Well that's kind of the problem though, isn't it? All that effort for the machine to sometimes correctly draw the regression line between the right and wrong answers in order to solve a trivial problem. A 6-year old kid would only need to learn the alphabet before being able to count it all on their own. Do we even realise how ridiculous these 'successes' sound? So a machine we have to "train" how to count the letters, is supposed to take over the work which is orders of magnitude more complex? It's a classic solution looking for a problem, if I've ever seen one.
