"it's the heart of their business" but the fact that it's a fundamentally alternative business model from anything they've taken a cent of revenue on is important to note.

It's like if airbnb bought $5B of Manhattan real estate. Yes, it's "the heart of their business" but also - wow.

Sure - but I think it's always been the expectation that Uber/Lyft/Sidecar before it went bellyup were participating in the sharing economy only as a stopgap until autonomous cars are available.

With Airbnb, I don't think anyone expects them to pivot into owning their own property. There's no real benefit.
