This is a letter signed by the most lauded AI researchers on Earth, along with CEOs from the biggest AI companies and many other very credible professors of computer science and engineering:

"Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war." https://www.safe.ai/work/statement-on-ai-risk

Laughing it off as the same as the Second Coming CANNOT work. Unless you think yourself cleverer and more capable of estimating the risk than all of these experts in the field.

Especially since many of them have incentives that should prevent them from penning such a letter.
