Because we are each an individual, infinitely complex being, our different physiological, environmental, and cultural variations bring us to infinite different endpoints. Like it or not, we all see the world slightly differently and our creative expressions reflect this.
We still need critical thinking. Ethical thinking. Systematic thinking. We still need to foster relationships. To build bridges. To coordinate. To orchestrate. These are human things. These are the skills that designers and developers need to cultivate and grow in order to continue to be viable in our AI age.
