This really seems like an overreaction to what I said.

The email thing is a metaphor. The point it attempts to make is not about obviousness of superiority of a technology, but that not all new technologies are novel. Sometimes they do an existing thing in a different way.

I do think it is inaccurate to say that everyone interested in the space is just in it as a get rich quick scheme. There is a very unfortunate and distracting amount of hype and speculation, but lots of people are just trying to build stuff they (correctly or incorrectly) believe will be useful, just like I've seen people do during the mobile boom and the web boom before that.

I share your skepticism, but not your certainty.
