In Rationalist circles, it's apparently common to share your p(doom) in casual conversation, with the understanding that it's putting a number on your hunch. Maybe it's not a good idea to post it on Twitter without elaborating?
On the other hand, in bookstores, you might see book titles like "The Uninhabitable Earth," "The Coming Civil War," and "If Anyone Builds It, Everyone Dies." Doom-mongering is a common part of the culture!
So what makes this particular tweet irresponsible?
Timing, maybe? People are on edge due to the HuggingFace incident.
