Sonic black holes have been studied experimentally. They are only weak analogs of actual black holes, so how much light they can shed on real black holes, I don't know, but it does seem to me that as long as they do have insights to reveal, we can't say that work on black hole information loss is purely mathematical. It's also possible that pure mathematical solutions will yield predictions that can be tested w/o a black hole. So I'm a bit skeptical of her take on this subject, though if work in this space is unrewarding and there's more rewarding work to do elsewhere, then that makes sense. But then, I am not a physicist! https://interestingengineering.com/sonic-black-holes-and-the-information-paradox
