> Think hard about this. Does that seem to you like it's likely to be a physical law?

Yes, it seems likely to me.

It seems like the ultimate in hubris to assume we are capable of creating something we are not capable of ourselves.

On the contrary, nearly every machine we've created is capable of things that we are not capable of ourselves. Cars travel more than twice as fast as the swiftest human. Airplanes fly. Calculators do math in an instant that would take a human months. Lightbulbs emit light. Cranes lift many tons. And so on and so forth.

So to create something that exceeds our capabilities is not a matter of hubris (as if physical laws cared about hubris anyway), it's an unambiguously ordinary occurrence.
