If I say "its inevitable that you will get into an accident while drunk driving" and you say "I've been drunk driving for years with 100% no accidents" I would assume you are being dense.
But I'd expect nothing less from HN.
In the face of actual data, and reproducible tests - isn't saying something like "well it didn't happen to me" dense?
The comparison might be insensitive, so excuse me for hurting your feelings, but I don't see how its invalid.
A more apt analogy then would be someone saying "My database runs with 100% uptime for 3 years, so there is no reason for me to keep backups"
