Many of the antibiotics are variations of the natural antibiotics produced by fungus and other bacteria, so it&#x27;s not a <i>new</i> arm race. It&#x27;s clear that not all the bacteria become resistant to all the natural antibiotics, because it usually increase the metabolical cost.<p>I think that in the long term this will be a draw, we will need to discover new antibiotics, some bacteria will discover new resistance. (For the more nasty variants we can have to use other tools like vaccines.)
