general moral of the story being, if somebody is doing a field jump, watch out:
whether it's William Happer doing climate science,
or Roger Penrose doing computer science,
or Sabine Hossenfelder doing developmental biology,
the fact that they're Physicists doesn't necessarily mean they know what they're talking about when the subject is Not Physics.
(for a non-physicist example, cf. Linus Pauling on the subject of Vitamin C).
