Well I don't think I said I'd purposefully give such a killer switch to an alien race, I just said we don't know.

We are all aware of the reasons to be pessimist, because of all the books and movies, but there are reasons to be optimist too: advanced technology may come with advanced ethics, for instance.

This isn't about "giving" the button to an alien race.

You criticized the original poster's sense of pessimism for holding the only parsimonious, evidence-based and logical position on the subject.

Have whatever fanciful opinion you want to on the subject, but pretending it's based in anything but wishful thinking is naive.
