What a strange sentiment.
The world would be better without nuclear technology! Yes, it can be used to generate electricity in a much cleaner way than other technologies, but its potential to kill so many people has shaped geopolitics for generations. If we could get the energy without the destruction, that would be ideal, of course. But there's an unacceptable chance that nuclear weapons will kill everyone I care about.
I think AI is actually similar. It's really useful for all sorts of stuff - I'm running multiple agents writing code as we speak. But it's also going to make the world much more dangerous by giving people the ability to kill and spy like never before.
There are better arguments than the water thing.
