This is going to get really hairy. Who gets to decide the protected classes? The classic ones grouped by race, religion, gender, etc will be too crude when computers are judging. Imagine some weird class like people who are old but don&#x27;t wear prescription glasses - perhaps indicating that they&#x27;re too irresponsible with money to be able to pay for them. Nevermind that they&#x27;re an exception whose eyesight is OK if that data isn&#x27;t visible to the computer. There could be all kinds of unexpected special cases like this that lead to individuals getting generally bad treatment throughout life.
