AI tools don't always work the same for everyone. A voice helper might not understand some accents, a face-scan might fail for darker skin, an app might only run on an expensive phone, captions might miss the words a deaf classmate needs. When a tool leaves someone out or treats them unfairly, the brave and kind thing is to stand up for them: notice who's left out, say the tool is at fault — not the person, speak up to a trusted grown-up or the people who made it, and find a fair way to include everyone.
