I think this is easy for pretty much anyone that's an active HN user, but is it for your parents or grandparents? It's they who matter a lot. It's why WhatsApp was so successful, it passed the Grandma check. Signal might, but onboarding is "hard" (and the nerds argue and that's all others hear and then do what... Use telegram? Lol). But it's why Matrix isn't gaining popularity, because frankly until creating servers is a one click install it's not going to get mass appeal (same for any federated app).
It's the old PGP joke: how do you decrypt a PGP email? You email the sender "I can't decrypt, can you send it without encryption?"
