Antibiotics are developed in an ever smaller amount due to the difficulties of discovering new ones. Bacteria, on the other hand, keep "finding" more ways to render antibiotics ineffective, and they are doing it faster than new antibiotics come to market. It seems that by a simple qualitative assessment at some point in the future all antibiotics will be ineffective.
However, there are 2 things I could think of that can suggest otherwise:
- Antibiotics which were rendered ineffective long ago can be reintroduced since it's possible that the bacteria mutated away from their defense mechanism. This would allow for cyclic reintroduction provided we have enough types of antibiotics to sustain the cycle.
- Antibiotics which bacteria can't defend against.
Are any of the above 2 possible futures? Can it be (at least theoretically) proven that antibiotics in point 2 can exist? Are there any other methods to "win the antibiotics war against bacteria" (assuming we are losing it as I assessed)?
