Forbidden Technology:

• AI without direct human oversight: Although they coexist with AI, any system that cannot be audited by human operators is banned. The memory of insular AIs that prioritized efficiency over human life is still very recent.
• Autonomous replication swarms: Any nanobot capable of self-replication has been prohibited after incidents of uncontrolled growth.
• Emotional surveillance systems: Considered ethically unacceptable, they were responsible for massive privacy violations and psycho-social manipulation.

Lost Technology:

• Open neural interfaces: The knowledge required to create implants with full access to the nervous system has been lost, or buried by collective decision.
• Mobile quantum generators: Although they use some quantum devices, it is known that compact, near-infinite energy sources once existed, but how they worked is now a mystery.
