Why this matters

Every day, AI produces language that sounds polished, confident and complete.

One of the most valuable thinking skills in the AI era is learning to notice when we're trusting how something sounds rather than what makes it true.

Today's workout begins by simply noticing that difference.

Workplace Scenario

You ask AI to draft a short update for your team on a project. The result is clear, professional and remarkably close to how you would have written it yourself. You have another meeting in five minutes and could send it immediately.
