Computers are already better at operating planes than humans, have been for years, and having read this entire thread, I don't think anyone has stated an opinion to the contrary. Every example of "humans being better" is an example of when it's all gone wrong, and the pilot has bailed the automation and/or the aircraft out.
Not strictly true in that I can operate my jet to the full limit of it's design capability and the autopilot can't. It also doesn't handle tailwinds on approach very well and/or anticipate big wind changes quickly which are all normal operational stuff day to day.
To beat the human you would need the next generation of autopilots and systems AND get them certified. So maybe some engineers can comment where we are with that but in the Airbus/Boeing world today we are still in the 80's really.
