Imagining Immortality

I am thinking of a scheme of how immortality might come to be real in the coming decades.

Perhaps, there will be storage tanks which will house millions upon millions of brains that will be alive and will be connected to a global network of news and everything.

When we are old, our brains will be put there and we will continue to live in a virtual sort of world or a mental world perhaps forever essentially being an observer.

Or, may be, we will have something like fish tanks in our homes where we will have the brains of our ancestors. Perhaps they will continue to live in our drawing rooms observing their progeny lead their daily lives.

How would that be like to have our grannies and granddaddies around? Or, at least, their brains.
