If you are limiting yourself to modern whatever, you are not going to find that a lot of science that affects everyday lives. Between the first results and practical applications, it can take many years. There is a reason Nobel prize winners tend to be old.

Less modern AI (aka. machine learning) is used all the time in science. I don't know of any commercial breakthrough yet, but there are some promising developments, like in antibiotics. If it materializes, that would be a very big deal.
