Machine intelligence has been on the rise since the 1950s. Already it exceeds human capabilities in many domains.

There is a common and well-known distinction between what you mean by 'machine intelligence' and what is meant by 'AGI'. Deep Blue is a chess AI. It plays chess. It can't plan a stock portfolio because it is narrow. Humans can play chess and plan stock portfolios, because they have general intelligence. Artificial general intelligence, not 'machine intelligence', is under discussion here.
