Interesting paper, but I find her delivery annoying. It seems that
we're
supposed to like a scientific result to the extent that it argues
against a theory she dislikes for unexplained reasons. And why does a
lack of fine-tuning argue against a multiverse anyway?

I think that the argument is that in a multiverse the majority of
observers exist in universes that are "fine tuned" for the existence of
observers, and therefore if you pick an observer at random it is
unlikely that it will be in a universe which is not fine tuned. That we
find ourselves in a universe that it not fine tuned (at least according
to the reviewed paper) is contrary to the expectations of a theory
incorporating multiverses. But I saw no quantification of how unlikely
this observation is, and regardless I'm cautious of drawing statistical
conclusions from samples of one.

One could incorporate the Fermi Paradox and suggest that we are in

capable of interstellar travel (or signaling), and wave away all
the uncertainties about those contingent probabilities.

They probably won't buy you much more beer unless you come up with
half-assed amusing things to say.

Sorry to disappoint. I blame the fact that I haven't had a beer

That's easily remedied:  I recommend Ichtyosaur pale ale.
