Bitcoin isn't for everyone, and I wouldn't push people who aren't comfortable with it to use it. Don't forget that Bitcoin also has a complex user experience and requires people to manage their private keys - many people, especially those without technical knowledge, can fail here. Users click "ok" without reading wallet's warning to back up their seed, or they store their seed in email drafts and lose coins after getting hacked, and so on. It's never too late to adopt Bitcoin, maybe in 5-10 years they'll come to it on their own, when they and Bitcoin will be ready.
