The flip side is: what if people aren't cutting emissions, or aren't cutting them fast enough? That's the actual situation we are in. Old social problems are even harder to solve than novel technological problems. If social change isn't happening fast enough to prevent the problem then I think we should try technological approaches. It's similar to how I would give Naloxone to someone overdosing on fentanyl even if the better solution would have been for them to not develop an opiate habit in the first place.

It is of course possible that both technological and social approaches will prove insufficient, and we'll go well beyond the "safe" level of global warming.
