Thanks for sharing. Your article feels a lot more intimate (less analytical) than the OP's. In particular, I was delighted to read the "Harm: loss of 3D vision" section because I now realize that my experience of rarely perceiving 3D isn't just me making things up. In particular:
> I can pop in and out of 2D and 3D vision at will, it’s just that 2D is the default, and 3D always feels more real.
I _wish_ I could do this at will. Probably once a month or so I notice that I have 3D vision and become entranced with just looking at things around me. Usually the feeling subsides within an hour, but it's rarely a "pop out" and more a gradual decline in how 3D things are.

And now I'm off to the wikipedia rabbit hole to learn more about this: https://en.wikipedia.org/wiki/Stereopsis_recovery
