Here are some other ideas to consider, which would be more practical than Dyson Spheres imo, and don't require more deviations in currently known physics than the construction of a star-sized solar panel:
- a civilization which has discovered a means to efficiently transform atomic mass into energy with arbitrary elements not considered good candidates for fission or fusion.
- a civilization which has a means to extract work from zero point energy.
- a civilization which is power efficient enough to never need an entire star's worth of energy localized in a single solar system. Note that John Von Neumann's brain consumed about 20 Watts of power.
Obviously, there is no right answer, because we aren't there yet. But the point of the original comment is that the ratio of media about Dyson Spheres to other speculation is really unbalanced for how impractical/uncreative (in this day and age, not when they were conceived) of an idea they are. No need to get combative about it.
Bayes’ Theorem and the fact that probabilities exist smoothly from zero to one on hypotheses.
For the same reason that you consider checking your kitchen table for keys before you contemplate their disappearance into the quantum froth.
Alternatively, “show me the code”. Let’s see what you’re talking about in specific instead of hiding in generalities.
