I'm wary rather than skeptical I think. There's clearly value here. Whether we're paying the true costs or not, however, won't be clear until all the VC fumes have cleared.

Much like the internet era actually - obviously loads of value, but picking out the pets.coms from the amazon.coms ... well, it wasn't clear at the time which was which; probably both really (we buy our petfood online) except that only one of them had the cash reserves to make it past the dot com crash.
