I don’t think it’s morally consistent to “warn” about the consequences while devoting your life to bringing about those consequences as quickly as possible. If I was in that position of power and truly believed what I was saying, I would devote my work to slowing down that process to give time for society to adapt, not speeding it up.
It’s more reminiscent of a religious group who smugly tells you that the end-times are coming, and only they are going to be saved. Except in this case they are literally bringing about the end-times.
