So usually, from the perspective of the story I just told to do with mining black holes, it's not clear what exactly will be broken about the universe if you could mine black holes somewhat faster than we can.

There are other symmetry concepts

There are other ways of thinking about it, in which if you could make a string that was strong enough to actually do it, if you could make a rope that was stronger than this bound, the various other things would go wrong.

There are various symmetry arguments that that can't happen.

But yeah, usually, often it turns out, if we have these bounds, that there's something that sort of saturates the bound or gets very close to the bound, and that's a sign that you're on the right lines with some of these bounds.

As in, if you have a bound, but you can't think how to get close to the bound, that's usually an indication that you need to think closer.

Because often these bounds are... Often these bounds, if you're clever enough, there's a way to get to the bound.

There's no rule that it has to be so, but that's often the case that someone will come up with a bound, someone will come up with... And there'll be a gap between the bound and how close we can get.

And usually...

more ingenuity will take you up to the bound.

Yeah, good question.

I started these investigations because it offended my intuition for various information theoretic reasons.

The idea that black holes could be mined, you know, with parametric speeds ups.

When I thought harder about it, the reasons why I thought that couldn't happen didn't really make sense.

So in this particular case, maybe someone will come up with a reason.

I don't actually have a particularly strong reason why they can't be mined anymore, except that they can't.

If you have a small black hole, you can get stuff out of them more rapidly.

The temperature of a black hole is inversely proportional to its size.

So one thing that people have talked about with black holes is using them to extract all of the energy from matter.

So, as you know,
