Question in Brief
The popular usage (I'm not sure of exact technical usage), limits the term "artificial intelligence" to only the "high-end" tasks; as if AI has something limited to "high-end". But "how much high" complication is required to define AI?
Same question Elaborated
We commonly consider "highly complicated" tasks/algorithms/computers to have "AI", say face transformation to age change, Applying painting-effect & assuming 3d rotational views on photos, breaking CAPTCHA codes, optical character recognition (OCR), Smartphone's owner identification by movement pattern detection through accelerometer, tracking social media user's likes and dislikes & thus matchmaking, etc.
Now, what about much less-complicated tasks/algorithms/machines? Say, could we call a simple pocket calculator to have some "artificial intelligence"? or can we tell that a Pascaline, or an old-day mechanical alarm clock, or a mechanical planimeter has some amount of artificial intelligence?
