I suspect the Celera 500L from Otto Aviation is going to make more impact. It's a rear-prop aircraft designed specifically for aerodynamic efficiency.

Currently they're equipped with RED A03
Together, they're spectacularly efficient, meaning a much lower carbon footprint.
I expect major changes in short-haul commercial aviation - but this craft can travel 4500nm at 460mph- so short haul could easily extend to a lot of what commercial jets are now used for.
Speaking as someone who was lucky enough to get a ride in a SST (long story) I can tell you that that kind of travel, not to mention LEO (really super-strat ballistic) is not for everybody.
