My two cents.

When the majority of adults over 35 to 40 have grown up in a automated society most specifically cars, buses and trucks and it’s a generally accepted norm. Then will start the move to pilotless aircraft. Until then the technology may be available but it will not be universally accepted. I believe pilots will be one of the last jobs automated and replaced by robots.

Doctors, lawyers etc. will be replaced before pilots in my humble opinion. I believe most on this forum will be retired before this happens for pilotless airliners.
