Incidentally, condoms work so well at preventing HIV from spreading that if everyone used them, the propagation rate of HIV would likely be dropped below a sustainable level, and AIDS would disappear. In Nevada brothels that use condoms, HIV rates are quite low.
I would agree with this statement. If everybody used condoms, then I could say the same thing about the propagation of pregnancy rates. If everybody used them, humans would likely be dropped below a sustainable level, and would disappear!
If it's worth hacking on well, it's worth hacking on for money.
