A huge swarm/sphere of solar collectors uses up precious materials (silicon, etc) that are far more valuable to use in ultimate compact reversible computers—which don’t need much energy to sustain anyway.
You seem to be bottomlining. Earlier you gave cold reversible-computing civs reasonable probability (and doubt), now you seem to treat it as an almost sure scenario for civ developement.
No I don’t see it as a sure scenario, just one that has much higher probability mass than dyson spheres. Compact, cold structures are far more likely than large hot constructions—due to speed of light and thermodynamic considerations.
Are you saying Dyson spheres are inefficient as computational substrate, as power collection, or both?
Because to me it looks like what you actually want is a Dyson sphere / swarm of solar collectors, powering a computer further out.
