Watch where this principle goes wrong on a setup you might build. Picture building your own personalized software, a setup tailored to how you live and work, with a morning brief, a short rundown of your day, as one piece of it. The interface will change over time, from typing into a chat model as of 2026, to voice, to glasses that carry world knowledge, to earbuds, to a brain-computer interface, and on to systems far more capable than today's; the move stays the same. The don't-apply path is to design the whole setup this month from last year's idea of what AI could do, lock in the workflows that fit that idea, and never test them again, so the setup quietly ages while the models underneath it get more capable. The do-apply path is to keep one running question, what just became reachable that was not before, and run a small weekly test against your own setup. When a model update makes a step you used to do by hand newly automatable, you find it in a 15-minute probe, not a year later, and you fold the new capability in before the gap between what you built and what is possible grows wide.
