Yes. Even beyond that, my understanding is that the fundamental issues with email are that: a. It is used as the basis for setting up a lot of accounts, but there is no clear way to establish identity with an email account. b. SMTP is very dated, and the large amounts of metadata (if not the entire body of every mail as well) that goes through it is doomed to be in plaintext forever c. Encryption is far from standard, PGP is very clunky and has problems of its own, and just doesn't have adoption. It works, somewhat, but it's not really good enough.
