What we haven’t pulled out yet is a black ball: a technology that invariably destroys the civilisation that invents it. That’s not because we’ve been particularly careful or wise when it comes to innovation. We’ve just been lucky. But what if there’s a black ball somewhere in the urn? If scientific and technological research continues, we’ll eventually pull it out, and we won’t be able to put it back in. We can invent but we can’t un-invent. Our strategy seems to be to hope that there is no black ball. – Aeon
