Imagine, for example, that the new development process is called Celeriflex. All the SV startups jump on Celeriflex like fleamen on a Belmont. They crank out awesome software and make huge exits. Some of those startup veterans use their payout to create consultancies to teach Celeriflex to other software businesses. They make money hand over fist. Then businesses whose primary product is not software notice. Their management hears good things about Celeriflex and orders the CTO/CIO to implement it. Eventually, the largest companies for whom software is a significant source of revenue keep doing what they have been doing for decades and use words culled from Celeriflex consultant documentation to describe it. At that point, Celeriflex is dead. The SV startups are using Speedcode now...
