But if building an app is as easy as voicing a requirement, and getting an updated version is as simple as asking for a change, then why should there be an ecosystem at all, rather than just bespoke on-the-fly apps for every single individual? As a tangent, I've been thinking about this in regards to the edtech space. For now, the focus is on GenAI tools for quickly building courses, but if we have AI with the combined skills of a Subject Matter Expert, Instructional Designer and Tutor, why would we need to build courses at all, if instead it could just teach anyone anything on the fly, based on their specific background and interests, and adapting immediately to their reactions? We've already been talking a lot about bubbles / echo chambers over the last decade, and I imagine that this will get a lot worse/better over the coming decade, depending on your perspective of the value of shared experiences.
