Educators weren’t convinced of the machine’s benefit, which prioritized individually paced learning not conducive to students of the same age moving through a grade level at the same time.
Elon Musk's X replaced its DMs with Chat, which is end-to-end encrypted but not by default. Users must set up a private-public key pair when they first use the feature and X says it uses "a combination of strong cryptographic schemes to encrypt every single message, link, and reaction that are part of an encrypted conversation before they leave the sender’s device and remain encrypted while stored on X's infrastructure. Once messages are received by the recipient devices, they are decrypted so that they can be read by the user." It's not watertight though.
