Matzke points to RandomEventGenerator & e-hostbrain as facilitating biodead ghost presence from Qr, p. 209, Deep Reality

Qr= Quantum realm

e-hostbrain = connects mind and brain using technology similar to the brain and likely even human ghosts in the Qr can control it... so this is likely a 'reanimation technology' that is more likely to work than cryonics which assumes mind is embedded in brain.

Rick's own etymologic invention - e-Ghostbrain, a psychokinetic PK device.... allowing the dead to "come back". Matzke says RandomEventGenerator is a precursor for that. A quantum computer would likely be able to host an e-ghostbrain. Already we see chatGPT and variants acting as IF they're inhabited rather LLM's.
