People talking to people is still how the world's standards change.And, an Ev Rogers quote, connected to the same idea, which is reinforced by the article:
Diffusion is essentially a social process through which people talking to people spread an innovation. [italics added]The two quotes, which are not adjacent to each other, suggest the idea (backed up by research) that technology is not spread by technology but by sociology (to keep the -ology endings). More than technology, though, is technique, which some authors have written about (I am thinking about the STS researchers, like Hughes and others).
I almost forgot: Teaching is essentially a type of diffusion of technique. This is one of my hesitations about MOOCs.
