Edit: From http://en.wikipedia.org/wiki/Fad
>>A fad is any form of behavior that develops among a large population and is collectively followed with enthusiasm for some period, generally as a result of the behavior's being perceived as novel in some way.[1] A fad is said to "catch on" when the number of people adopting it begins to increase rapidly. The behavior will normally fade quickly once the perception of novelty is gone.[1]<<
I'm not sure that we are yet in the "large population" phase even though this is like the third time I've heard about this new footwear.
http://en.wikipedia.org/wiki/Tarahumara_people The word for themselves, Rarámuri, means "runners on foot" or "those who run fast" in their native tongue according to some early ethnographers like Norwegian Carl Lumholtz, though this interpretation has not been fully agreed upon. With widely dispersed settlements, these people developed a tradition of long-distance running up to 120 miles (190 km) in one session, over a period of two days through their homeland of rough canyon country, for intervillage communication and transportation as well as to hunt.
They also have the tendency to eat when hungry, sleep when sleepy (as in, anytime / anywhere) which has threads to other "genius" discussions (lets call being able to run 100's of miles a type of "physical genius" for a thought experiment). I know when I do barefoot walking on a frequent basis my chronic lower back pain starts to dissipate.
Side note: We also aren't naturally meant to sit all day in an office chair, yet...
Note, I'm not necessarily advocating barefoot running. I do run on my forefeet, so I run in Newtons, for now.
Two things though: (1) Heel running is less efficient, results in higher impact forces and leads to more injuries than forefoot running. (2) The only reason most of us heel run is because we started running in sneakers from a young age.
Again, your second link, did you even read it?
That's pretty much the only thing holding me back from buying them or any of the funky new (curved bottom) shoe ideas, I know I would never wear them.

I'll never buy a "normal" running shoe again.
For regular walking/business shoes give Geox a try. The solid leather insole and lightweight build is amazing. The air transfer through the sole actually works too.
(This could be my foot's fault though, my smallest toe gets scrunched up in the shoe "fingers")
I have been turned away from places for wearing jeans before. I doubt they would allow me in looking like frog man.
It's more "those places" I was talking about. Sure, nobody is going to scoff at what I wear around my condo.
If you mean acceptable in semi-formal or even business casual settings, I would say that will just never happen.
The Merrrell trail shoe someone linked is a good example. I have a pair of pumas that are very similar, though a little more boring.
