It's the false positives that make me worry the most about Gmail :\ I sometimes get personal emails from family shoved in the spam folder - they're in my contact book, they're starred, they're relatively frequent emailers in both directions... but still, in to spam you go. The false-positives are usually so absurd, that I have to assume they have no boundaries for their ML-whatever. If it says spam because it has decided that contact books are only worth 90% positive signal, then into spam it goes. ML > any hard-coded rational decisions.
