Even if you don’t subscribe to the Dark Forest Hypothesis it’s extraordinarily unethical to violate the cosmic privacy of the entire human race without their consent- at worst it’s essentially summoning the obliteration of all life on Earth; at best it’s scientifically experimenting on the entire human race present and future without our consent.
