The noise aspect has been shelved and kept out of the debate, as many (wrongly) believe those electric aircraft will be silent. Well the engines are to a certain extend put the propeller blades are not, and multi high speed rotating props make an unpleasant high pitch noise. How the public , especially the people living under the routes will react and accept that new noise will be I believe one of the important acceptance factors ,
As to fully autonomous commercial operations, I just came back for a GNSS jamming/ spoofing meeting, and as long as this is not resolved I cannot see autonomous flights based on a GPS/GNSS infrastructure bring a viable option right now.
