Yes. And the people talking about "bringing the power of the Sun to Earth" are usually either full of shit or expect so little from their audience that they are effectively talking shit (or are making clickbait, what's the same). (And yes, there's a lot of fraud around fusion too.)
The people doing actual work don't use phrases like that in normal conversation.
But surely, anyone who's talking about atomic weapons must be invoking religious imagery and the old myths of divine retribution! They can't be talking about an actual technology capable of vaporizing cities and burning people into the walls as shadows - what a ridiculous, impossible notion would that be! "World War 3" is just a good old end-of-the-world myth, the kind of myth that exists in many religions, but given a new coat of paint.
And Hiroshima and Nagasaki? It's the story of Sodom and Gomorrah, now retold for the new age. You have to be a doomsday cultist to believe that something like this could actually happen!
