Insofar as I can tell, thermostats have a 0% chance of feeling pain (or as close to 0 as is logically possible), so I see no need to afford them moral consideration. If we had evidence suggesting that AI who could suffer currently existed, and if there was any overlap between the suffering-relevant pieces of that AI and thermostats, I'd start to worry about "killing" thermostats. It still seems like the chance of insects subjectively suffering is orders of magnitude greater than the chance of modern thermostats suffering.
I really enjoyed the ACX article; thank you for the recommendation! I agreed with a lot of the general points he was making.
Not sure about the "dignity" of e.g. plants, as I think there are plenty of ways to harm plants and animals that is helpful to humans. It's an interesting idea, though, and I do like the attempt to make a practical argument instead of a moral one.
In any case, while (to some extent) I care about the possible suffering of insects who are farmed in the trillions, I'm not particularly morally concerned about thousands killed for greater scientific gain. Could I ask generally what work you're doing with them? I'd be interested in learning more about it
2: Scott Alexander has written on this recently and it covers much of the same ground that we are covering here: https://astralcodexten.substack.com/p/i-will-not-eat-the-bug...
3: Some time ago I seem to remember the Swiss Government discussing a proposition to recognise the 'dignity' of insect and plants. Dignity was held to be a property distinct from suffering and I think part of the argument was that it was somehow mutual: damaging life in any form was harmful to the dignity of both the damager and the damagee. I have some sympathy with that idea. In other words, we should care about the bugs because we care about ourselves.
Disclosure, I do a lot of scientific work with Drosophila and this is something that I mull over from time to time as I slaughter them in their thousands...
