> I just don't see it. That’s because you haven’t tried. You only test what you know, what’s provable. The goal isn’t 100% validation of everything. The only goal is error identification. Surely you know something in science, like the distance to Proxima Centauri. Start with what you know. Then when something new comes along the only goal is to see which of those known things are challenged. Testing doesn’t buy certainty. It’s more like insurance, because it successfully lowers risks in much shorter time. Like with insurance there aren’t wild expectations it’s going to prevent a house fire, but it will prevent unexpected homelessness.
