Glad to hear you're better! :)

Sure, we can't _know_ that, but the paper still presents fairly compelling reasons to be skeptical/update away from near-c speeds.

>our model predicts we'd see alien volumes if the speed was much slower.

But when we look to the sky and see nothing, we should also increase our credence that the aliens just aren't there, or that they never become grabby. Why wouldn't you mostly update in _those_ directions?

We cannot just assume grabby aliens into existence and then pretend that our observations only tell us about what they must be like, when our observations clearly have significant bearing on whether they exist at all.

The question is what is feasible for our descendants in say 10Myr. Seems hard for us to know that, and our model predicts we'd see alien volumes if the speed was much slower.
