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.
