Nobody can predict the future accurately.

But in my opinion about these:
It will be very difficult and seems impossible because banks are under the control of the government and also world banks. And they will not let it be.

It may also, and it may be not fully, but most of us, well, and I am wondering and imagining like the movie with robots 

And about other probabilities, they may be possible, but of course, they will face difficult and hard problems, obstacles and challenges. Because sometimes they will be dominant, not replacing all. Because every country may have a different culture. And maybe there will be other types of new future again
