I think you seriously underestimate just how many lives antibiotics save. Sure, for your tooth extraction they were completely unnecessary and your doctor is either a bit of an idiot or there were other compelling reasons to suspect that antibiotics might be beneficial. But healthcare-wise I would not want to go back to the 1920, no sir. Without antibiotics, medical routine procedures will become life-threatening again (that said, I don’t share the article’s pessimism; yes, it’s bad – but there will be solutions).
