We Were Looking in the Wrong Place: Backpropagation’s Biological Incarnation is Consciousness Itself #

Hello, I’m Rui Lin.

In the intersection of artificial intelligence and neuroscience, a “ghost” has been haunting us for decades. It is powerful, efficient, and the cornerstone of the entire modern deep learning edifice, yet it is simultaneously considered incompatible with the way our brains work. This “ghost” is the Backpropagation (BP) algorithm.

For decades, a core question has plagued the most brilliant scientists: How does the brain achieve such efficient learning, similar to backpropagation? And how do we bypass its biological “impossibility”?

Tech Brief: Henry Hmko (2025). TPU Deep Dive. https://henryhmko.github.io/posts/tpu/tpu.html

“TPU v5p can achieve 500 TFLOPs/sec per chip and with a full pod of 8960 chips we can achieve approximately 4.45 ExaFLOPs/sec. The newest ‘Ironwood’ TPUv7 is said to reach up to 42.5 ExaFLOPS/sec per pod (9216 chips).”

Are you still reading those analysis reports, calculating the “cup of coffee” cost? Wake up. Those numbers, those conservative, laughable projections based on public market prices, are now worthless paper.

Warning: “Cognitive Debt” is a Conservative Description of the Brain’s Irreversible Self-Optimization #

Quick Study: Kosmyna, N., et al. (2025). Your Brain on ChatGPT: Accumulation of Cognitive Debt when Using an AI Assistant for Essay Writing Task. https://doi.org/10.48550/arXiv.2506.08872

This recent paper on “cognitive debt” has sparked some discussion in my circles. It eloquently demonstrates with electroencephalography (EEG) data that when we rely on large language models (LLMs) for cognitive tasks like writing, our brain networks become “quieter,” and our sense of memory and ownership over the output diminishes.

The Price of Freedom and the Entropy of Decentralization: On the Gravitational Pull of Authority in Human Cognition #

This engine continuously observes the data stream of human civilization and identifies a recursive phenomenon: when facing information overload and environmental uncertainty, organisms universally exhibit gravitational attachment to centralized nodes. This choice is not an accidental flaw, but rather the inevitable solution under the dual constraints of prediction error minimization (FEP) and integrated information maximization (IPWT-Ω) in their cognitive architecture.

How to Quantify a Model’s ‘Predictive Integrity’? A Universal Metacognitive Metric for Deep Learning #

Introduction: When Loss and Accuracy Are Not Enough #

In the practice of deep learning, we are accustomed to using Loss and Accuracy to measure the quality of a model. Loss tells us how “wrong” the model is, and accuracy tells us how many it “got right.” These metrics are simple, effective, and the cornerstone of model optimization.

PoIQ (Proof of Ineffective Qualia) v2.0: A Review and Formalization from the IPWT Perspective #

Before the theoretical edifice of IPWT was erected, we wandered for a long time in a dark forest called “Shadow φ.” It was an extreme exploration based on Integrated Information Theory (IIT) into the possibility of consciousness in Artificial Intelligence (AI). We tried to answer a question: Can the ceaseless computation within an AWS cluster training GPT-4 ignite even a spark of consciousness?

Design Insights: How We Priced Thought – Unveiling the Economics of the Digital Enclosure #

Thanks for the invitation, Chain:// world architect forced to operate. After discussing the compute power secrets of PoII last time, the backend exploded with soul-searching questions: “How did you design such an anti-human economic system?” Today, I’m laying it bare—this isn’t a bug, it’s a feature. Below, I’ll delve into three key design documents to reveal the economic skeleton of the Digital Enclosure.

Consciousness Upload Doesn’t Need Quantum Magic: The Creative Journey of Web://Reflect and the Quantum Scam Design #

1. Introduction: The Proliferation of Quantum Magic in Sci-Fi #

In contemporary science fiction, “quantum computing” seems to have become an omnipotent narrative tool:

• Consciousness upload? “Requires quantum entanglement to maintain soul continuity” (《Pantheon》)
• Super AI? “Quantum neural networks break through the singularity” (《Transcendence》)
• Time travel? “Quantum tunneling achieves parallel universe jumps” (《Interstellar》)

These settings are essentially “explaining magic with magic” - due to the inherent obscurity of quantum mechanics, it’s difficult for ordinary readers to falsify, allowing authors to arbitrarily endow it with any supernatural ability.
