right, but atoms are just energy and we are not limited to chemistry in trying to create them. In the amount of time it will take for the universe to go dark it would be sad to have not yet figured out how to create the elements in massive quantities, and because the atoms are all composed of the same pieces we can also convert them by playing with electrons neutrons protons while probably also gaining energy from the conversion, there's really nothing stopping us from spawning new stars except our scale of civilization and limited knowledge of science, and I think both of those things are accelerating. If anything, we can just ask AI how to do it in 15 years.
