I've already heard it said that if you have the notion that Amazon is not competing with your business then you've probably just not been following its activities lately.
> if you have the notion that Amazon is not competing with your business
you would think OP is talking about industries in general, much like how AMZN is moving into a bunch of other industries like online payment processing (Amazon Pay), grocery (Whole Foods, Amazon GO), etc. They certainly aren't moving into every industry, probably because these industries already are low-margin or don't have a clear path to growth under Amazon disruption.
Banks: Amazon Lending
Cars: Zoox
Semiconductors: Annapurna Labs on the design side. They aren't entering the fab side, but who is anymore?
Vacation planning: They've vaguely entered it a few times, but withdrew. They used to offer travel bookings directly on Amazon in partnership with Expedia. That disappeared, then they made tentative steps towards bookings with Amazon local. That's not to mention how they already own a significant chunk of the retail side of travel.
But the fact that a list of business _not_ engaged in is that short, _and_ that a bunch of subsequent comments dispute a number of them, is freaking insane.
