alt Hacker Newshaving worked there. Amazon has toxic managers, culture that turn ICs against each other. no tech vision. insane politics. low caliber people gatekeeping.
Their stock will go up the next year or two only because of their luck of partnering with Anthropic (back when they were a distant second choice to OpenAPI)
but the partnership is fake marketing. Amazon uses TPUs more than it uses graviton, it trains on GCP, and Google owns a larger percentage because they were much earlier investors, despite amazon investing more money.
