Congrats to Signal, this is a great step!

At Tutanota we also use the Signal protocol to build post-quantum secure encryption for email and drive: https://tutanota.com/blog/pqdrive-project

Post-quantum secure encryption can't be developed early enough. In the end all our data today will be at risk of being decrypted in the future - unless we secure it now!

That's not exactly the most compelling blog post. Way too many buzz words. Why would end-end cloud storage even be using public-key cryptography? You're sending the encrypted data to yourself forward in time.

Not for storing the data, no, but public-key cryptography is needed for sharing encrypted files.
