When it finally hits the bottom and it's for sale at non-unicorn prices, I fully expect to either see Amazon buy it up and merge it into Flex, or else Google/MS/Whoever buy it so that Amazon doesn't.
Amazon has enough cash on hand to do it, isn't afraid of losing money for years on end, and enough legal power to defend it (see: Google buyout of YouTube). The extra work density of both programs combined would make the sum more valuable than the parts.

I'd think Otto in particular would be enormously beneficial to Amazon. Amazon loves robots, and anything that reduces shipping costs (and times) would be incredibly valuable to them.
