I opened this link and was hoping for a conversation about how cryptography (not cryptocurrencies) has not made significant advancements in user experience. Not that the article wasn't interesting, but I've long felt that while crypto-primitives advance, the UX of cryptography APIs is still poor across all languages: It's hard to not screw things up, it's hard to understand for newcomers, and there is poor interoperability and no real common encryption file format (maybe gpg, but that's too complex and not widely adopted in popular tools).
This was really off topic. My apologies for that, but I feel like I had to get that off my chest :-)
