AF-S has been around since 1998. People don't have to be "careful"
Well said Bushfiva. Stop spreading FUD (Fear, Uncertainty, Doubt) ... OoT.
Also, to be honest, people using Nikon's consumer DSLRs are probably better off using AF-S lenses, preferably ones with VR too. There are lots of good ones out there... the 18-70 and 18-200 are both fine examples.
Non AF-S lenses are noisy too !
