Strong AI vs Weak AI

Strong AI can be defined as building real intelligence artificially.
That is to say, a human-made intelligence that
has points of view, self-awareness, and emotions same as humans.
However, this is still an assumption working on
the concept of creating AI agents
with thinking, reasoning, and decision-making capabilities like humans.

Weak AI is the present development stage of artificial intelligence
that deals with the creation of intelligent agents and machines
used for helping humans and solving real-world complex problems.
Examples of weak AI are Siri and Alexa.
