Both are a possibility but we can't make choices about the meteors. ;-)
Nuclear incidents due to negligence or malice are many orders of magnitude more likely, and get more likely the more waste we make and the longer we keep making it.
Europe was a bombed wasteland less than 100 years ago. Luckily that was before nuclear power plants.
Have a look at the situation in Sellafield, or the Asse II mine. Negligence has caused problems many times already.
Chernobyl is in the news recently due to drone strikes. Had it been a solar plant it wouldn't have been.
Anyway - the point is that the expensive security efforts and precautions are needed, not optional, and the historical safety record is no guarantee for future safety.
>We also know what an antinuclear path leads to
Not yet - we can hope that it leads to solar, batteries and synthesized fuels.
China has shown that it is possible, which was the last hurdle IMO. Now it's just a matter of doing it.
