Reply to comment by jfecju in A broad-spectrum synthetic antibiotic that does not evoke bacterial resistance by geoxol

Life is not infinitely adaptable. Of course there can be an broad range antibiotic that is impossible to develop resistance against no matter how much it's spread around in places where it shouldn't be. Finding such an antibiotic of course is a separate matter. Not very hard to test its performance though, bacterial colonies can climb concentration gradients or they can't.

Sure, life isn't infinitely adaptable. However, we need to keep the patient alive as well. Selectively killing off bacteria is the crux

Not infinitely no, but then we also don't have infinite compounds we can potentially use and the constraint that it not kill a patients cells means that it must be possible for some life to adapt to survive it meaning potentially the bacteria can. I'd say in practical situations it will be impossible to develop something bacteria can't adapt to.
