Not sure if you can really avoid this type of freak accident by hiring more/better people. AF might have one of the more traditional approach to aviation with more and more experienced crew per aircraft than any other western airline. It's more of a mindset, less of a training issue. This will change after the final report or at least we hope so.
Even with the best training in the world (which AF probably doesn't) you can never avoid that one pilot gets it wrong. The one who gets it wrong was the one at the wrong time at the wrong place, the holes of the cheese fit together and bummm there we are. As someone correctly mentioned, there were dozends of similar incidents of pitot icing on A330/340 during the last few years and never ever did something happen.
I remember being in a simulator with a fellow captain in a well reputable TRTO when we trained TCAS/ACAS and the captain beside me turned out to be completly inproficient in his reaction, pulling up to the hard stop when he heard Mr. Airbus calling "climb, climb". When we asked him, he said he never trained TCAS before. It's as unexcusable as the AF FOs, but it happens, there is always something happening, because we are not living in a perfect world. And when several mistakes happen at the same time, people are dying. And it will happen again, but in other circumstances and with other failures. Just because there were two incapable persons in the cockpit doesn't mean that our aviation system is wrong, training is wrong and bean counters are wrong. Because 99.9999% of all pilots would have handled the incident completly sufficient and safe.
We can safely argue that there must have been a lack of knowledge and/or training in Air France, after the second pull up exercise, so this problem will be solved, hopefully, soon. Then everyone back to his/her station and then we can finally finish this discussion. Anyone agree?
