Cognitive Fitness

Developing our capacity to think, learn, and choose as AI becomes more capable.

Daniel Holguin

Cognitive Fitness is a book I plan to write. Right now, I’m reading broadly and taking in as much as I can to learn about the subject and figure out how to write it.

The thesis is that as AI takes on more of the work we once had to do ourselves, our ability to learn, reason, question, adapt, and create becomes increasingly important. These capacities can be trained, protected, and expanded. AI could free us from repetitive work and give us more room to be creative, but realizing that possibility means continuing to develop our own minds and retaining the ability to choose how we use them.
