Okay, but if they write another open letter or give another keynote proclaiming the end of the world then you owe me a beer.
I am not making any claims about mathematicians as a collective group, because mathematicians have many diverse views on AI and can't be lumped together into a single "they" (as your comment seems to imply that they can). In fact, some academic mathematicians even work for the AI companies. Your comment seems to imply that if a group of mathematicians publish some statement, then that statement must speak for all mathematicians, but that's simply not true.
