Lots of people talking about how this looks like 2000's clipart, (and I'm not here to disagree) but seems like no one is talking about how these appear to be full 3D models that can be manipulated. AirBnb is actually being fairly subtle (small spinning animation on load) considering how over the top that could get, quickly. People have been doing small versions of this with 3D css transforms, but this is a step further.

Inevitably these things are fashion, and big companies want to have just slightly unique experiences. Usually that means doing something hard that the average site will struggle to replicate for a while, be that squishy UX animations, elegant minimalism, now 3D.
