2030 seems to soon IMO. It will happen one day, but probably won't be common in my life time. I just can't see passengers feeling happy without hearing and seeing the pilot.
Manufacturers will have to be brave, they could design this genius aircraft that passengers are too scared to fly on. Not to mention who wants to trust a fully automatic plane with 100s of lives with nobody monitoring it. The main bugs in aircraft are only realised once they enter service....that could be 1000 lives too late.
