I’m glad you pointed this out.

Dyson was thinking it would be unstable. His vision was of large orbiting solar panels. But there was no controlling what sci-fi authors did with the concept.

I was joking of course, which I often am even when I don't include an emoji.

Freeman Dyson actually was unhappy with the concept being called by his name. See "Dyson Sphere" in wikipedia for an interesting read.
Just as zero is not equal to infinity, everything coming from nothing is illogical.
