What do you think of the most massive LVK black hole so far?

We’re all at the big GR+Amaldi conference this week, and the LIGO/Virgo/KAGRA folks have been announcing their most massive gravitational-wave event so far, GW231123. I was asked about it by a few journalist, from both New Scientis (“LIGO has spotted the most massive black hole collision ever detected”) and the American Physical Society (“Heaviest Black Hole Merger Flouts a Forbidden Gap”). Exciting stuff indeed! My thoughts on the hierarchical-merger formation idea are that it’s likely but not obvious at the same time.
