Instead of attempting to predict the future, future-proofing online courses is about making them easier to update, more inclusive and more useful to students, even as context changes. It is future-proof when the design is strong enough to cope with change. Links die. Readings date. Professional standards shift. Platforms change. Students arrive with different expectations, needs and levels of digital confidence. Artificial intelligence has moved from novelty to routine before many course teams agreed what to do about it. Of course, no course team can predict all of this in advance. But teams can design online courses that are easier to update, easier to access and more likely to remain meaningful when the context changes.
