Yes, you’d better have a risk/cost-model.
I avoided mentioning any specific Jubjub problems to try to minimize mind-killing effects. But since you’ve brought up climate change, which is usually coded as a left-wing issue in our political discourse, I’d just like to mention that there are also Jubjub problems with a very different political coding, e.g. dysgenic pressure, a reactionary right-wing issue.
Ah, the fallacy of gray. When any particular person evaluates any particular issue, the details are going to matter. That doesn’t mean it’s a fallacy to identify two generic approaches to problems like this.
