Hmm... it's hard to imagine that fishing with dynamite ever caused species extinction; trawling industry definitely did. I don't think it's a fitting analogy, but I get what you're trying to say. I'm not arguing about the damage. The damage this human invention will cause is guaranteed. Just like plastics have. The answer to that is not "ban plastics completely" - kinda late for that, innit? The answer is "put resources into plastic research, make safe plastic possible". Maybe if we make safe, better AI, it will help with the plastic? If there's anything I've learned about humans - first, we probably cause a lot of damage.
