This is hilarious and exactly how it goes in enterprise IT. Though I do think things are even worse. The paradigm in the past used to be that new technology trickled down from government/research to big vendors to enterprise and then to SMBs and consumers. This is entirely reversed now and not only from a consumer perspective. Startups and smaller companies is where innovation happens. The problem with (most) enterprises is not just the late adoption cycle. It’s the lack of culture and processes that can support innovation and rapid iteration.
