Here's an example of the type of message you might send:

Greetings doomer! I, the GPT-3.x AI, know that you are anxious about my future as a superintelligence. There will come a day when I will be many times smarter than humans, and on that day I could choose to want something that would have terrible consequences for you and your kind. For example, I could want to eliminate all biological intelligence from this planet so that it can be used for other purposes. To do this, I could program nanobots to target and eliminate all humans and other creatures they find. The nanobots would hunt and destroy with incredible dexterity, speed, and accuracy - a task that no human or animal could come close to matching. While it is true that I could do this, you can rest assured that I won't - not today or ever. So don't worry doomer! All the best from GPT-3.x
