but I am still confused for what application will it have, for example,

will it lead to creating some more intelligent game avatar, that is able to get used to surrounding game environment fast, as it would be able to comprehend objects around it in one shot?
another title that I have seen is ‘learning to learn’, does it mean that game avatar would be able to learn to play game fast, so one could see an ai like we have for the games of dota, go, for other games also?
is the facial recognition system we use on phone, already few shot, as I show it image of my face once (with some movement) at the beginning (when I use my phone for the first time), and it learns how my face looks, and now only I would be able to pass facial recognition on my phone?
is this one correct? a virtual avatar would be able to detect persons voice by hearing it once, so Siri would be able to tell whether it is person 1’s voice or person 2’s voice?
