I had 2,500 stock option in AMZN in 2001 at a strike price of something like $7 or thereabouts that I sold all of them at around $40. Plus some RSUs and made around $100k. Thought retail margins would mean AMZN was never profitable and eventually that side of the business would crash and burn. Meanwhile, I figured that the trick to building out your own infrastructure cheaply (basically "just be really fucking cheap and fire people who do expensive shit like build out SANs") would catch on and the margins would disappear from the AWS/EC2 business as everyone just built out "internal clouds" for 10x cheaper than buying from AWS.
