Re: IBM Watson
Good point about knowledge. I feel that machine learning's first task would be to help businesses allocate resources in an efficient fashion. For instance, if user sentiment is negative for a certain feature of a product that is driving sales figures to be low and similarly, user sentiment is positive for a feature, causing sales figures to increase then, identifying the variables at play would deliver value to the business. The variables could be locally correct (due to culture) but, universally incorrect. Nevertheless, value would still be generated for the business.
