We know you're scared s***less of any kind of human progress. If it hasn't been done before, it must be "... lies straight from the pit of hell."
We try to explain that things will be better with improvements in the human condition. But your fears just won't let you go there. We understand.
The survival of the human race depends on overcoming our fears of the unknown... "to boldly go where no one has gone before."
That famous line was a metaphor by-the-way. While fictionally "exploring strange new worlds," the story-tellers were really exploring the human condition. How we treat each other. How we react to change. How we overcome our beliefs in what is possible on encountering the "impossible". And how we embrace it a grow as a result.
We know your fears for they are ours too. We've chosen to let our rational minds hold our fears at bay, for there is no way out of fear but through change.
The only way to remove a threat is to learn. We either learn to understand that it is not really a threat, or we learn how to mitigate or overcome it. We'll keep trying.
