Well... They said the same in the industrial era. There are a lot of things to consider, for example: - AI might not like to work, as we don't like to work - You suppose that if you create AI then the AI can create a more intelligence AI and this to the infinity. We don't know if the intelligence is unlimited or limited. We might have reach the top intelligence. (note: the more intelligent the brain the slower it is, and a bigger brain does not relate to intelligence)
