> Humans discover that the cool and useful thing is toxic as fuck, but only after years go by. It takes years for the awareness of the toxicity to become widespread enough for everyone to concur it’s a problem.
There's no reason for there to be years between discovery and action. It doesn't matter how quickly the discovery ripples through lay society. Once it's known that something is harming and/or killing people, it should be stopped.
What if the alternatives are the kind of thing that could possibly be worse but we don’t have enough experience with them yet to know that they are worse?
Often the known bad thing is better than the thing you don’t know to be bad yet.
