Supposedly the ideal planet would be bathed in a perpetual sunset so i guess you’d need a hell of a lot of solar collectors to be effective, if they developed that far. Also i read that the star might be unstable and dims even more, plunging the ideal planet into a kind of fimbulwinter, maybe for years. Perhaps they hibernate in a regular cycle like the spiders from vernor vinge’s a deepness in the sky. The frustrating thing is we don’t yet know the key ingredients for life to work here let alone elsewhere: take the moon away and can life start? Who knows. Are circadian rhythms essential for life? Who knows.
