IMO, this is a huge part of why so many startups fail so badly.<p>Google glass might have caught on as a 50$ toy, but at 1,500$ it&#x27;s firmly into the realm of things people working at Google would buy, and that&#x27;s about it.  What&#x27;s really interesting IMO is they could have made a 50$ version of the basic concept, but it was simply not on anyone&#x27;s radar.<p>In theory, these blinders are why startups can show up and eat incumbents lunches.  But, when starts are drawing from the same talent pool there making the same kind of mistakes.<p>Net result, way to many food delivery services.
