My word...
I don't have the hours some have on here, but I have enough to self preserve and self criticize, and one of the things I've learnt, that my experience has given me, is to keep my mouth shut regarding the abilities of a fellow pilot who has 'gone down'.
It's fantastic to speculate about possibilities, that's how we get the mind working and learning, but come on, a bit of respect for a pilot who has been involved in a very traumatic experience, one which we have no solid knowledge about what caused it.
All we can do is theorize, so let's wait until the report before we question the pilot's personal skills/safety?
