We talk about a wide variety of stuff on LW, but we don't spend much time trying to identify the very highest-utility stuff to discuss and promoting additional discussion of it. This thread is a stab at that. Since it's just comments, you can feel more comfortable bringing up ideas that might be wrong or unoriginal (but nevertheless have relatively high expected value, since existential risks are such an important topic).
Low-quality or otherwise low-investment attempts at convincing people to make major life changes seem to me to run a strong risk of setting up later attempts for the one argument against an army failure mode. Remember that the people you're trying to convince aren't perfect rationalists.
(And I'm not sure that convincing a few researchers would be an improvement, let alone a large one.)
