Durable Skills

AI fluency means using these tools to amplify human judgment, not replace it. We believe people with these skills will thrive as work and technology continue to evolve:

Awareness: U nderstand yourself and others .

Judgment: E valuat e information and mak e decisions in complex situations .

Adaptability: L earn, adjust, and stay effective through change .

Connection: C ommunicat e , collaborat e , and build trust .
