Do We Need Humans to Replicate Machines?

It's extremely unlikely that we will, that there'll be humans around ar. Maybe we'll have died out. It's possible that we will survive long enough that the machinery will be able to replicate itself. I think it's more likely, but who knows, that we will still be needed at the point where this planet is uninhabitable by humans and we die out. And then that would be the end of it. But let's suppose it carries on. You talked about fidelity. We should note that the increase intat th fidelity's very interesting because geans are copied with incredibly high fidelity. There are lots of mistakes made. Accidental combinations, a mutations happen ouow
