Signal is all about making good cryptography usable for the general public. If you actually use the "safety numbers" to verify the identity of who you are communicating with then you have real guaranteed end to end encryption. Unfortunately not everyone does that. People that really really need to be sure probably use something super simple like PGP after they take the time to learn how.
