Because I’m seeing this in “serious” articles, Dyson spheres are—literally—a joke.
The paper from Freeman Dyson is literally a fully purpose-written joke making fun of early SETI efforts, with a cascade of ever more implausible assertions leading to “we should be surrounded with these spheres so let’s look for them”.
They’re a joke making fun of gullible people who don’t think things through.
Now gullible people who don’t think things through (like Sam Altman) are using the term like it’s a real thing that could actually work.
