As my readers know, establishment is clueless only because they forgot half of their Hertzsprung-Russell diagram. The oldest stars do not shine. They are called "exoplanets/planets".
It will probably take a few more dozen years before they finally admit they are standing on an ancient star older than the Sun, the solidifying remains of a many billion year old object which has life on its surface in its vast complexity.
