AWS is a (collection of) service(s) which can scale and have low marginal cost of reproduction. Fire Tablets are a real thing you can buy, but they are shit so nobody does.
I get that you meant “physical” but this blur between “advertising isn’t a useful thing for an economy to focus on” and “services are not real” is a bit of a jump!
Cloud services don’t just exist on their own accord. Datacenters are physical and real!
