      Elements with a proton number less than or greater than iron become more stable as they approach iron, and so, over very, very long timeframes, from random quantum tunnelling effects, will favour being iron over being other elements.

      Thus, in 10^~1500 years, virtually all atoms in the universe will turn into iron, assuming protons don’t decay (which may or may not happen).

      Iron-56 is one of the most stable nuclei, along with nickel-62, so after untold time lengths, due to standard fissile decay/spontaneous fusion (possibly due to quantum tunneling), all baryonic matter decays into iron-56, and a little nickel-62.
