A similar argument, I would guess, would have been made by secretaries in the 1980's if Ed Kotch had decided to type up a few of his own memos on this new thing called the word processor. Programming is getting easier and easier as languages improve and processors become faster. It's no surprise that it is becoming democratized. I think it's great Mayor Bloomberg is learning to code. He will probably really enjoy it and it will increase his general literacy about technology. I can't argue against anyone wanting to learn something.
