I would argue that its strength lies in another area: It gets people excited. It makes people start thousands of new projects and companies, millions read all the news articles and a huge crowd invests a lot of money into the space.
And, of course, it gets people excited because it hits a nerve. It promises a change of power structure in the world. Away from monolithic, opaque, political structures to democratic, transparent, border-less systems. Changing the role of everyone from a helpless observer to an actice participant.
Obviously the build-up is messy and over-promising but it may very well change the core infrastructures of how the whole world currently operates - economically, politically and socially.
