Serena recognizes something subtler than simple cheerleading—that women's achievements can either multiply each other's power or get hoarded as proof of individual exceptionalism. When one woman's success becomes a standard that makes another feel she must be equally exceptional to matter, the system wins; when it becomes a ladder, the system shifts. A young girl watching a female surgeon operate doesn't just gain inspiration; she gains permission to stop proving she's "one of the special ones" and start building what comes next. That's the difference between admiration and acceleration.
