I agree, however there is no defining line for the non-tech savvy that determines what is bleeding edge, and what isn't. Is Ruby going to be around in 5 years? If Ruby is around, will I be able to hire developers easily and for a reasonable price? These are concerns that drive businesses for whom tech is a necessity but not the core of their business.

So the business owner relies on the tech provider who hopefully isn't in a full on romance with the newest framework/language just because it's new.
