I do not see it as a master strategy. It is just something that happened. Similar to having no plan of having million fakeish Chinese brand selling crap on Amazon.com. But ones they are there then Sure, why not . May be in few year a lot of crashed and burned AI talent will be looking for boring corporate IT/AI job and Amazon will be around to offer that. And if does not happen there will still be ton of other work to do for Amazon.
