Paul Krugman (Nobel laureate in economy) said in 1998 that the internet is no biggie. Many companies needed convincing to adopt the internet (heck, some still need convincing).
Would you say the same thing ("If it helped as much as its claimed, there wouldn't be any need to try and convince people they should be using it.") about the internet?
I would, unironically.
Thing's called a self-fulfilling prophecy. Next level to a MLM scheme: total bootstrap. Throwing shit at things in innate primate activity, use money to shift people's attention to a given thing for long enough and eventually they'll throw enough shit at the wall for something to stick. At which point it becomes something able to roll along with the market cycles.
