Anyway, it feels completely ridiculous to talk about it in the first place. There will never be a mind that can quickly and vastly improve itself and then invent all kinds of technological magic to wipe us out. Even most science fiction books avoid that because it sounds too implausible.

Says the wooly mammoth, circa 100,000 BC.

Sounding silly and low status and science-fictiony doesn't actually make it unlikely to happen in the real world.
