Here’s a quotation from Ben Thompson, who has been carefully watching, thinking about, and writing about technology with expert precision for a very long time.

There are three parts of any new paradigm in technology: doing current use cases better, coming up with a new business model, and creating entirely new use cases.

In my world(s), the first two items on the list are much easier, and executed much more frequently, than the third. Perhaps that’s because creating new uses cases, new stories, new examples, new evidence, new marketing assets takes a lot of time. Which of course is no excuse.

Though, P.S., I should have known that “use case” has a very specific meaning in the world of technology. A quick Google search helps to clarify things, though I recommend looking at words before images (like the ones below).
