Re: The human pilots just do the easy bits...
The landing part is more interesting.
Computer aid is now used to way under 500 feet on some large airports in low visibility conditions - LHR (on a foggy day), BJS (smoggy day), etc. They simply cannot operate if the pilots do not use it as they have to close.
So the idea to switch to manual at 500 rings rather hollow.
From this perspective, you gotta love Luftwaffe's operating practice. There, the pilots from the long haul fleet regularly take a rota to fly a Junkers Ju-52 http://www.dlbs.de/en/Fleet/Junkers-JU-52/ to remind them that what does it mean to fly a passenger airplane with no computer aids.
