Look, I think I get your POV, I really do.
You seem to think airliner ops are trivial. Many here would disagree with you.
You seem to think the technology for fully automated/autonomous ops is pretty much here, but perhaps not quite ready for pax ops just yet, though all it needs is some unspecified technical advance.
If anyone fields an an objection as to why autonomous ops might not be a player at the moment you come up with a vague or trivial fix ( add another engine - really? , redundancy - yes but what/where/at what level), or failing that throw in comments about peoples mobile phones or ABS..which doesn't move the argument anywhere.
I can promise you many others (some working in AI) think we're decades away from autonomous ops.
Anyhow this is just a debate, the answer is at least 20-30 years down the road..I'm out.
