I've read it, but (perhaps I'm wrong, I'm a biologist turned to computational biology so not expert on epidemiological models ;) didn't the author (and similar Stats News post) argue that it is too optimistic, IOW the opposite that you were arguing in the post?

I don't mean this is as a criticism, but it struck me as some dissonance as I was reading.

I've also heard that there might be criticism to other models like the Imperial College one, but so far I've never found anything with some substance.
