I suspect this has been answered on here before in a lot more detail, but:
Also, specifically in AI, there is some precedent for there to be only a few years between "researchers get AI to do something at all" and "this AI is better at its task than any human who has ever lived". Chess did it a while. It just happened with Go. I suspect we're crossing that point with image recognition now.
Do you expect AGI to be qualitatively or quantitatively better at thinking than humans?
Do you think there are different types of intelligence? If so, what types? And would AGI be the same type as humans?
EDIT: By "intelligence" I mean general intelligence.
Why expect AGIs to be better at thinking than human beings? Is there some argument that human thinking problems are primarily due to hardware constraints? Has anyone here put much thought into parenting/educating AGIs?
