An interesting point was brought from a WSJ article [1] about Paige's situation: "Page’s condition has worried the collective tech world and Google investors". Unfortunately, the article doesn't elaborate on this claim so it is tough to determine how true this is but like I said, it is an interesting point and thought-provoking.
