FaceID is one of the most important technology invented. Imagine if Apple somehow was open to license it and make it universal like Bill Gates wanted to make PCs universal. It can make driver licenses, passports, credit cards, student IDs, insurance IDs - all of these can be things of past. You go to grocery store and simply pay using your face. You want to pay online? Simply look at FaceID device that is now standard with all new computers sold. This is 100s of billions worth of business to make so much legacy gone. Security and identity is now (hopefully) solved but unfortunately still all behind walled garden.
