The idea that we have to fully understand something to use it or make it safe is fundamentally absurd. Bread makers of the past didn't know yeast existed but they used it like masters and shaped the world. Einstein said "we don't know one millionth of one percent about anything." Life still goes on. We form complex societies and structures. We have medicines that cure terrible diseases not because we understand the deep inner workings of every protein but because bold people tried things and experimented and found a way forward despite their relative blindness. This is the way of the world. We have to build out societies for the bold and the builders and the spice traders and the people who take risks and create a better world through the infinite creative loop of life. Never give in to the people who would slam the breaks on the world and built our lives around fear and phantoms. The fearful have never contributed anything to great story of the world other than noise and suffering. And they often enable the very things they fear by creating societies of violence and rigidity and madness in an attempt to stop imaginary future disasters. Nothing can stop the infinite creativity of Man. Except fear.
