It is all a part of it. The challenge is what is in the database to begin with. Here is where the community dictates things. An algo isnt going to do anything is people do not participate in training it.
As for the retrieval, that is a problem for Hive.
It is up to the people and the community to decide how diverse they can build the data, add the data. Wider the data, better gambling of it by AI.
Without a doubt. I am not sure most realize how all this works. The more each person inputs, the more the output is improved.
Both on the individual and collective level.
