Fusion energy has been "coming in 5 years" ever since 1960. Just like Gallium Arsenide will replace Silicon. Except neither has happened and the reasons are physics!!
So sometimes innovations don't work because of things like economics, geoscience, politics, funding, and other times it's fair to say that it's the physics that doesn't play. It communicates more by using an accurate word, while "everything is physics" communicates nothing at all?
Gödel just found it.
