Being somewhat pessimistic here. As someone who actively hacks DNA, I believe that we can address this problem responsibly with the development of new and novel antibiotics for antibiotic-resistant bacteria. There are significant challenges in the biology but there is technology being developed that will significantly reduce the cost and time needed to develop new antibodies.
For example, my company TeselaGen (http://teselagen.com) has developed a cloud based platform for biologists to design, build, and test a large combinatorial set of DNA constructs. Some of our customers use our software today to easily and effectively test an incredible number of DNA devices for identifying and developing useful antibodies.If you have an understanding of genetics and cloning you can try out the software yourself.
