With launch costs set to drop aggressively I wonder if space based solar becomes viable sooner than expected. Iirc the NASA estimate was something like $200-500/kg launch costs. I wonder if concentrated solar in the form of thin mirrors can change that.
Musk's most recent estimate of the eventual cost per kg on starship was 10 usd/kg. He may be considered an unreliable source at this point, however.
