You do know that the A320 was designed nearly 40 years ago, right?
There have been a few improvements in the electronics/automation arena since then
You do know that aeroplanes designed 40 and 60 years ago are still the main product that the world's major manufacturers of aircraft are still producing right? I imagine that you would also be aware that the time frame to produce a new aircraft from scratch using existing technology is at least a 15-20 year proposition right? So designing an autonomous aircraft from scratch that would be commercially viable and acceptable to the world's airlines, regulators and airspace designers is not going to happen within the working life of a 20 year old F/O yeah?
