Do we really know that Boltzmann brains outnumber observers living in solar systems that fluctuate into existence?
Sure, a solar system is a much larger fluctuation than a brain, but a brain requires a fluctuation to produce an extremely complex and unlikely combination of matter whereas a solar system is just a lot of hydrogen in one place. A solar system can also last for billions of years and evolve quadrillions of times more observers, each of whom will experience millions of times the number of observer moments as a lone brain before it decays back into vacuum.
Solar-system-based observers should have orderly experiences unlike vacuum brains, so if they outnumber the brains, the average observer should observe an orderly universe. They are also distinguishable from us, since they observe a starless sky. That means they’re still a problem for theories that predict them.
