In the last few years, we have seen an increased awareness that PGP/GPG is a dinosaur of 1990s crypto, and it does not satisfy the need of modern users for secure communication.

PGP model has many perverse effects: like creating a single point of failure where all sensitive communications are compromised with cracking one single key, which sooner or later quantum computer will crack.

Possibly PGP can be fixed and have forward security added etc, but for now many security researchers do not advocate to use PGP.

UPDATES:
Now are there any trustworthy alternatives on this planet? I believe there aren’t. I would recommend users NOT to trust anyone who says them some app is secure, like in this article which advocates Signal/What App . They are going to be disappointed.
