The glasses that make money disappear, magically

I had read one or two other less than enthusiatic reviews of a new attempt by a company to do augmented reality glasses in a way that people might want to use, unlike the response to Google Glass.   But boy, this write up from the Washington Post is really negative, and starts with this startling fact:

Magic Leap, a Florida start-up, has raised $2.3 billion (yes, billion) from investors on the promise it can mix computer-generated images into regular human sight.

It is really hard to understand what they were thinking - it sounds wildly unlikely, after the failure of Google Glass, that there is going to be a market for such a clumsy looking device.
