Sorry for the misunderstanding. Maybe I didn't phrase my thoughts well. Amazon's problem is providing "interesting" problems. Interesting problems also are usually very niche. The problems that Google and Facebook are trying to solve don't necessarily overlap with those being solved by Amazon. My comment was more aimed at the viability of Amazon finding the most capable people it could. It seems to have removed "culture" as a positive and the only thing that it has going for it is "interesting" problems. Without them Amazon will rot. So far they continue to allow people to work on cool things.
