It's blogs and sites like Udemy. Their business model depends on people needing to learn new technologies constantly. So when they tell you "MVC is dead" or "Rails is dead", there is a direct profit motive in it for them. They tell you everyone is using Backbone.js, so you move. Then the next year it's Angular. Backbone is outdated, no one uses it anymore. Then the next year it's React. The blogs drive the technology shifts in order to get clicks. And every time the technology shifts, Udemy sells a million tutorial videos at $10 a piece. Everyone gets up to speed on the new thing just in time for the blogs to find new clicks and Udemy to find new videos. Meanwhile the real world still runs on Laravel, Rails, Flask, and Postgres.
