That Paul Graham essay is fantastic. It really helps me to put into place things that I've been realising over time. For a long time I've had showdead enabled and I always go looking for the buried comments to see what I'm not allowed to say. I suggest everyone does.
Fukushima did not. Check out the Netflix documentary Inside Bill’s Brain. The last episode discusses nuclear tech, and was rather enlightening to me. Fukushima was discussed, and I learned a lot about why that happened.
Really? I'm more pro-nuclear, and to me it seems like every time there's a post about it there's a pretty balanced argument in the comments about it. It's incendiary, yes, but the debate does happen, and the antis seem just as passionate as the pros.
I think it's less about "any sort of doubt" and more about the doubts that I actually see put forward, e.g. "Fukushima proved that nuclear energy is not that safe."
I'll downvote that not because it's a doubt about nuclear energy safety, but because it's a pretty bad assertion.
