When the crypto crowd complains about PGP being obsolete, they don’t just knock PGP, they very often mention alternatives. One of the most frequent recommendations is instead of using ordinary email and trying to bolt PGP onto it with individual contacts, use an encrypted messenger. I have been using Signal for four years now with the same install moved from phone to phone, and it has worked just fine. I can chat with my friends and relatives with E2E encryption, while I could have never got them to use PGP at all.
