Software like GPT should be a tool, not a crutch. There is a lot that people can do to maintain their mental acuity over the decades, and I know first-hand the difference between doing it and not doing it. Those who do nothing, and especially those that increasingly lean on crutches, soon learn just how much worse it can get. Even a genetically lucky brain can be squandered.

Watch the Huberman Lab podcast and ask yourself if you'd like the kind of mental acuity that 48yo Dr Andrew Huberman effortlessly demonstrates every single time. His worst off days are better than most people in their prime. That's what is possible when people actually research and apply tools to improve their own health and abilities directly. There are a lot of rabbit holes this can go down, but just acknowledging it as an axis worth working on is the most important first step.
