Do you have something in mind? Both of your examples are referring to spontaneous results out of a random system, and that’s not what any engineering is. If it were, we would have ~0 modern technology at all.

Sure it’s possible that there’s some barrier, but no one can point to what it is or even what it hypothetically could be, so why assume it’s there? Especially given, again, we know for a fact that a random process already achieved it.
