> The thing is in all those cases a human built and trained an Ai to do those things.

The terms you're looking for is supervised learning vs unsupervised / self learning.. Both have been heavily studied for decades. AlphaGo learned on a library of past games, but they also made a better playing AlphaGo Zero which is entirely self-taught by playing with itself. No human input needed.

So... NO, it's NOT "all those cases". You're just behind on the current state of AI development.
