I see from his biography that he was the Chairman of Northern Rock when it had to be bailed out. Perhaps his knowledge of banking is equal to that of aviation.
However, he missed two important points. Firstly, autolands are not applicable in lots of situations for all sorts of reasons eg crosswinds, RNAV/visual approaches, defects occurring in flight or allowable items. Which brings me to the second point that if you require someone that needs the skill to land the aircraft manually then you have to train them and keep them current so they may as well be in the aeroplane. Never mind the whole host of day to day stuff that we deal with eg traversing the ITCZ being a good example as mentioned above.
The lesson surely of AF447 is that when the aircraft is degraded in some respect then it is quite likely that old fashioned piloting skills are required to ensure a safe outcome.
