I predict by 2030 humans are back to paper and personal messengers just so we can get some peace from slam.

I look forward to iMessage latest revolution from Apple. It takes a revolutionary to bring human connection back in the feel of your hands. Send incredibly beautiful textured linen paper, folded to perfect, tucked in a pocket of starched paper, sealed with the latest in molecular bond technology. Upgrade with iCut Pro, a shimmering blade in silver, gold, rose gold, and matte black that pairs incredibly with iMessage to open each embodiment of human connection with a swift, crisp cut.

Remember they literally had, and cancelled, Steve Jobs's real-postcard-from your-photos passion project.

You'll only be able to talk to someone if your Apple watch reports that your heart rate is acceptable for the call, and they won't be able to answer the call if their Apple watch says they're too agitated.
