@GraceKind Thanks for bringing this to my attention! The paper notes:

The opinions expressed in this article are those of the author (at the time of writing). They do not necessarily reflect the views of his employers or the institutions to which he is affiliated.

I think it would have to be reposted from the Google DeepMind website or Twitter or otherwise endorsed to qualify.

It seems likely that a company like anthropic would sponsor a paper that at least explores this.
