But human perception isn’t just a passive conveyor belt. It’s heavily top-down. When you imagine an apple (your “mind’s eye”), your brain runs the process in reverse. Your higher-level executive networks and memory centers (the embedding layer) send a signal backward down into your Primary Visual Cortex (V1), forcing those early edge-and-color neurons to fire. You literally simulate the sensory experience. (Fun fact: if this feedback loop is physically missing or disconnected, you have Aphantasia—a complete inability to voluntarily visualize mental imagery [1].)

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.
