I’d say it’s worse, they’re usually trying to imply that the people engaged in the activity aren’t sufficiently allied with their pet political or moral causes. If you engage with their tweet-sized sniping the conversation inevitably leads to “why aren’t they spending their time and resources addressing climate change/wealth inequality/poverty/etc.”
Such arrogance. It's funny that you mention climate change because this project is a non-negligible use of energy that is indefensible even in the context of advancing "pure mathematics." It's literally computation for the sake of computing more things that haven't been computed before. The only end result is that we can say we computed more things.
