Would an AI be allowed to answer questions on Quora?
There is a topic for Quora Bots (Quora feature). I messaged Quora founder Charlie Cheever in 2011 suggesting… a voluntary, opt-in “bot-zone” as a sandbox for question answering bot projects. To a large extent working with question answering bots would depend on the as yet non-existent Quora API. However, question answering bots may also conflict with the work of Quora founder Adam D’Angelo on his Vicarious (company)… “building software that thinks and learns like a human”.

Would all the data from Quora be helpful for making A.I. like Watson be more humanlike in its conversation? If so, how? If not, why?
Versions of this question seem to get asked over and over again on Quora, above. Generally, conversational AI and in particular question answering systems are built on top of question/answer pairs, and machine learning can be applied to question/answer pairs. The biggest stumbling block at the moment is the conspicuous absence of a publicly available Quora API. Quora co-founder Adam D’Angelo may already be at work on this through his stake inVicarious (company).
