I think of "context change" as multiple technologies and trends that chaotically converge into a critical mass of opportunity. It's easy to spot looking backwards, but impossible to predict. You're just the nth individual trying this new/old thing, and now the market supports it, and for a while things are great, until you overreach, you don't reach enough, you're legislated, a new technology comes out of nowhere, there's a pandemic, there's a tectonic shift in global markets, etc.
