The path of least cost/energy

We've passed that inflection point in the cost/quality curve of visual effects where it is almost always more cost effective now to use compositing than to use physical locations, props, and extras. Not the case yet for actors, but you can still save a lot of money on everything else. It's amazing how much of the mundane shots in almost every TV series now are just executed in a computer.

This a precursor of what virtual reality will do to reality given all the shadow costs of reality. A producer ordering VFX in place of sending a crew on location is pursuing the most cost-efficient strategy. What Tyler Cowen refers to as the complacent class of people sitting at home watching Netflix on a Friday night rather than paying to go out to a crowded public place is also just cost efficient (or energy efficient) behavior.
