I'm not jumping out of any windows based on a Musk tweet. And It's not imaginary, but some people's perceptions are that it is something it is not. Hence the windmill comment.What is anyone doing that is jousting at windmills? The very use of the phrase implies it is imaginary. It most definitely is not. That Musk is concerned is not enough of a wake up call? That Stephen Hawking is concerned about what we do in space, is that a real concern? That we all know our virologists are playing gain of function with deadly viruses is that a concern?
Just trying to understand what you believe is real and what is imaginary?
