I say the same goes for business models. About 15 years ago I spent 5 years in the early SaaS space, and it was extremely difficult to convince IT Mgrs and CTOs that software as a service was not some evil plan. Today, it is hard to sell software that is not sold as a service. Why? The old guard management is gone, and tech is managed by people who grew up with SaaS and/or are afraid of managing their own hardware infrastructures.
