[$] Layers and abstractions

In software, we tend to build abstraction layers. But, at times, those layers get in the way, so we squash them. In a talk at SCALE 17x in Pasadena, CA, Kyle Anderson surveyed some of the layers that we have built and squashed along the way. He also looked at some of the layers that are being created today with an eye toward where, how, and why they might get squashed moving forward.
