There are many competing definitions of Intelligence:
"The ability to use memory,...experience,...reasoning,...in order to solve problems and adapt to new situations."
"The ability to learn,...and make judgments...based on reason."
"Intelligence is a very general mental capability that, among other things, involves the ability to reason, plan, solve problems,...learn quickly, and learn from experience."
"The ability to learn facts and skills and apply them."
"...ability to adapt effectively to the environment, either by making a change in oneself or by changing the environment or finding a new one...a combination of many mental processes..."
"...the general mental ability involved in calculating, reasoning, perceiving relationships and analogies, learning quickly, storing and retrieving information,...classifying, generalizing, and adjusting to new situations."
"Sensation, perception, association, memory,...discrimination,...and reasoning."
"...the process of acquiring, storing in memory, retrieving, combining, comparing..."
"...a cluster of cognitive abilities..."
"Any system...that generates adaptive behaviour..."
"...getting better over time."
"...effectively perceiving,...and responding to the environment."
"The ability to be able to correctly see similarities and differences and recognize things that are identical."
My Asa H 2.0 (and some other AI experiments) meets all of these criteria and is intelligent. The question then is, how intelligent is it.
Humans and AIs don't occupy the same niche. They don't eat the same foods, reproduce in the same way, occupy the same habitat. etc. So asking which is "more intelligent" or "superior" is going to be an approximation at best. Different people have different levels of intelligence and there are different sorts of intelligence as well so we should be quite happy to have an AI even if it is not as smart as the very smartest human. It can still be useful. But for those people who seem to be satisfied only with "human equivalent" AIs I can't help but note that:
performs control tasks better than humans
has more short term memory than humans
has more reliable memory than humans
can have more senses than humans
can multiply by diskcopying
can (via telepresence) be in many places at once
AIs have been able to:
handle statistics and probability better than humans can
operate with more consistency than humans
can remotely maneuver helicopters better than human pilots
can create patentable inventions (i.e., Koza's GAs)
can prove math theorems humans have not been able to solve (i.e., the Robbins problem)
can evaluate loan applications and predict student success better than humans can
can plan/schedule transportation problems faster than humans can
can solve arithmetic/accounting problems faster and more accurately than humans
On the other hand:
Humans currently have a richer set of emotions than AIs do.
Humans are better at natural language than AIs are (though an AI is better at jeopardy than humans are).
