There already is gate keeping though, and that gate is manned by corporate which, ironically, is how so much bloat can sneak in at your expense.
I am not fond of gates either; for as long as your skill can produce capital value it will be gatekept in some capacity. I'd rather see that gate moved closer to our side if it must exist.

You are saying people will need to be certified to be programmers?
This is just gate keeping and considering how accessible computing is, it would never work anyway.
