Brain in a Jar: The Ultimate ASI Path to Immortality and Freedom
NoSignificance152 · reddit · 2026-08-03
A Reddit user sparked a deep discussion on how humans might achieve immortality and absolute freedom in the era of Artificial Superintelligence (ASI) by preserving their biological brains.
The author argues that keeping the original biological brain in a secure vault maintained by an ASI is superior to mind uploading, which suffers from the 'clone paradox'—you cannot prove the digital copy is actually 'you.' Under this setup:
- Remote Avatars: The brain could connect to a global network of synthetic bodies, swapping between bioprinted enhanced humans, robotic chassis, or even animals.
- Pseudo-Teleportation: Instead of physical travel, one could rent a physical 'shell' at the destination. The ASI could pause neural activity during transit to eliminate speed-of-light delays.
- Digital Sandboxes: People might choose to live entirely in self-governed hyper-realistic simulations, raising profound ethical questions about what should be permitted in a private universe where everything feels authentic.
