The wikipedia page about antibiotics resistance (https://en.wikipedia.org/wiki/Antimicrobial_resistance https://en.wikipedia.org/wiki/Antimicrobial_resistance) adds some interesting points on why we are falling behind on the race for the discovery of new antibiotics. The TLDR is it's currently not economically convenient for big pharmaceutical companies to invest in antibiotics research but several measures have been taken in order to make it better and, hopefully, will allow us to catch up on the race.
