No I don’t worry about AIDS becoming airbone, but when you look at the historical record of pandemics they are much more a problem than would appear of first glance. Pandemics that wipe out 1/3 to 1/2 the population and that appear out of nowhere are far too common over the last 2500 years for us to be complacent.

For roughly 2300 or more of those years we didn't understand how diseases spread or how to treat/prevent them.

But that doesn't mean we humans are "safe". Knowledge is power but its not a vaccine.
