Do weeds keep adapting to weed killers?

    Yes. The principle is the same as the reason bacterially-caused diseases continue to evolve resistance to new antibiotics. Killing off all the weeds or bacteria that are susceptible to an certain chemical gives a significant evolutionary advantage to the rare bacteria or plant which has a chance genetic variation that gives it a greater chance of surviving exposure to that antibiotic or herbicide (weed killer).

    The only way to completely prevent the evolution of resistant would be to never try to control disease or weeds. However there are many strategies we could adopt to slow the development of resistance to the benefit of public health and agriculture.
