No it isn't.
You've read the book?
The point is, particle scientiests have shown no fundamental progress in the last decades, and claimed several times there will be progress for sure with the next billion EUR. But this has not materialized.
Hossenfelder argues that the "for sure" part comes from the perception of beauty by the scientists, and they have no other basis for being convinced there is possible progress than that the current theories are not beautiful (e.g. no quantum gravity, no unified theory, no super symmetry).
Climate scientists have shown massive progress over the last decades.
"[...] because they found a climate scientist who also disagrees."
It's not that "one" scientist says there is no progress, all scientists agree there is no progress in particle science (except showing a particle exists that everyone was sure existed already and waves that everyone also was sure exist, no new insights). So listen to the scientists about their progress, when billions of EURs and broken promises have not brought any progress and decide if they should get more, or the billions are better spend on scientists that make progress (climate, health, AI, ...).
