I have seen at least one example develop in real time. You typically spent years building before you had a platform, then lack the enthusiasm from senior leadership to invest the next 12-18 months with no new features and hard to quantify - maybe no - returns. Then you get displaced by newcomers who are "platform native"; what this really means is their engineering misteps haven't been discovered yet, or even if they guessed correctly the world has turned and made their previously correct solution now a failing one. And now we have something called "AI-native" that is going to solve this once and for all with some sort of magic, and you can't lead these companies unless you truly believe in the magic.
