- Just so the virus. It either "bumps" into a cell that is "receptive"
- or it doesn't. The virus has no intelligence. It depends on
- physics to encounter a suitable host. If it doesn't, it dies.
- If it does, it sets up shop. The HIV is exactly the same. It
- has to encounter a receptive cell or you don't get infected.
- The problem is the word "distinguish" which implies some sort of
- discriminatory behavior. The seed doesn't really distinguish the
- rock. The rock just doesn't provide a suitable environment for
- the seed to sprout. Sorry it was not a clear example.
