We have to interact with everyone so no one feels left out or ashamed; these negative emotions can kill curiosity and creativity.

Our brains actively construct a model of the world, which is our actual experience. Incoming sensory data serves mainly to verify and correct this internal model. A familiar example is predictive texting on smartphones. You start typing, and the phone anticipates the rest of the word.

By 1970, with a budding awareness of computers, I envisioned a future where the cumbersome administrative tasks of gaming could be offloaded to computers, transforming gameplay into something as visually captivating as television but with the added allure of interactivity.
