Difference between weak AI and strong AI?

Question

can you please explain me both terms and what are the major differences?

How can you determine whether an intelligence is weak or strong?

Why these terms?

Answer 1

Q: How can you determine whether an intelligence is weak or strong?

A: There is no strong AI in existence (yet). Therefore everything is weak AI or less.

Explanation from here:

Artificial Narrow Intelligence (ANI): Sometimes referred to as Weak AI, Artificial Narrow Intelligence is AI that specializes in one area. There’s AI that can beat the world chess champion in chess, but that’s the only thing it does. Ask it to figure out a better way to store data on a hard drive, and it’ll look at you blankly.

And

Artificial General Intelligence (AGI): Sometimes referred to as Strong AI, or Human-Level AI, Artificial General Intelligence refers to a computer that is as smart as a human across the board—a machine that can perform any intellectual task that a human being can. Creating AGI is a much harder task than creating ANI, and we’re yet to do it. Professor Linda Gottfredson describes intelligence as “a very general mental capability that, among other things, involves the ability to reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly, and learn from experience.” AGI would be able to do all of those things as easily as you can.

Both are AI, but one is for single purpose only, so it is regarded as less powerful, hence the term weak. The other is Human level AI, so it is called strong.

But the terminology does not stop here. You also have Artificial Superintelligence, which is even better than Human AI:

Artificial Superintelligence (ASI): Oxford philosopher and leading AI thinker Nick Bostrom defines superintelligence as “an intellect that is much smarter than the best human brains in practically every field, including scientific creativity, general wisdom and social skills.” Artificial Superintelligence ranges from a computer that’s just a little smarter than a human to one that’s trillions of times smarter—across the board.
