  There’s a huge difference between “doing fine” in a modern society and in nature where she wouldn’t have survived. The article mentions her case is also rather atypical.

  Opportunity cost is a hell of a thing. After the surgery, she grew introverted, and many of the friends who had supported her in third grade drifted away. Her family and doctors knew her ambitious goals of college and a career would be a struggle, but others were more negative, even cruel. A teacher at a technical high school said she doubted Santhouse would ever be able to do more than answer phones. Even the Johns Hopkins doctors said she'd never drive. Yet, "I was full steam ahead," Santhouse said, recounting how she got her driver's license at 17, excelled on the high school bowling team, and pushed herself through college and on to a graduate degree. "I wasn't going to let [the brain surgery] stop me." I don't think its fair to say that this would be considered a full life by many. But, given your view, perhaps you would volunteer to have this surgery done to prove this? Edit: I suppose you would probably be fine if you consumed the news (propaganda) and embraced leftism.
