But I think the real value -- and this is definitely in Google's favor -- is providing this functionality for photos you have taken in the past.
I have probably 30K+ photos in Google Photos that capture moments from the past 15 years. There are quite a lot of them where I've taken multiple shots of the same scene in quick succession, and it would be fairly straightforward for Google to detect such groupings and apply the technique to produce synthesized pictures that are better than the originals. It already does something similar for photo collages and "best in a series of rapid shots." They surface without my having to do anything.
The current best theory and understanding of the evolution of the universe is that it will reach maximum entropy (heat death). There is no cycling when this happens. Can you cite what theory or new discovery you have come across that somehow challenges the heat death hypothesis?
