I've been following for awhile what happen on Facebook AI research and I believe AI won't ever rule the world.. here's my reason
Basic reason why humanity want to have an AI is because we think that we need more precision, more fast, more strong, more intelegent machine that acomodate all what we told it to do.. That why, I can simply put it that humanity want better servant.. let me bold it, SERVANT.. and (we could open history book) that servant who "Reasoning" aren't good servant.. AI are Reasoning.. AI will need to know why they need to do something that they told to, and humanity won't buy that kind of "Servant".. it would be useless machine, it would be bad for bussiness, and it will be a waste-of-money research.. so no one gonna buy it, no one gonna sell it, no one gonna make it.
