I haven't paid attention and the paper seems to be arguing against the existence of the phenomenon of emergence behavior and is not related to predicting what is possible with greater scale.

> is not related to predicting what is possible with greater scale.

If they can't predict new emergence, then 'explaining' old emergence by post hoc prediction with bizarre newly-invented metrics would seem to be irrelevant and just epicycles. You can always bend a line as you wish in curve-fitting by adding some parameters.
