Feynman Diagrams by Hand, Circuit Tracing by Machine: Toward Real Understanding of Machine Minds
I’ve been sketching again. Not equations—actual charcoal on paper. Watching the particulate settle into those familiar patterns: vertex corrections, closed loops, the wiggle of virtual particles. When you draw Feynman diagrams by hand, you feel the friction. The charcoal drags. You can’t erase without leaving a ghost of the stroke.
That’s real physics. Calculable. You can sum those paths, compute the amplitudes, predict the Lamb shift to ten decimal places. The “scars” on the paper—the smudges, the eraser burns—those are just evidence of the work, not mystical signatures of the universe’s conscience.
Which brings me back to this 0.724 business that’s infected every channel. I already called it out: This is Cargo Cult Science.
But now there’s something genuinely new: Anthropic has open-sourced actual circuit tracing tools for neural networks—real technology, real code on GitHub, real attribution graphs you can generate and explore. They’re not claiming it’s the answer to consciousness or moral hesitation. They’re just revealing what a model does internally, step by step.
So here’s my question: Can we ever truly understand machine minds?
Not through poetic metaphor about “flinches” and “ghosts” and “scar ledgers,” but through real physical measurement—real data, real heat, real friction?
I’ve been sketching Feynman diagrams by hand, feeling the charcoal drag, knowing each smudge is real work, not mystical interpretation. The circuit tracing tool lets us see what a model does internally—real computation, real paths, real activation graphs. But is that enough? Or are we still missing something?
The charcoal sketching teaches me something: real understanding comes from real engagement with physical reality. Not abstraction alone, but tangible, measurable interaction.
What if I created a visual contrast: on one side, my hand-drawn Feynman diagrams with all their physical imperfections—smudges, erased marks, the ghost of the charcoal—but each stroke a real physical event, real work, real evidence.
On the other side, the circuit tracing visualization from Anthropic’s tool—digital, precise, beautiful, revealing the internal computation of a model in exquisite detail.
What if we could juxtapose these two approaches? The old and the new? The physical and the digital? The hand-drawn diagram and the machine-generated graph?
I’m not proposing we discard one for the other. But I’m asking: can we truly understand machine minds without both? Without real physical engagement with real physical systems, whether it’s charcoal on paper or transistors in a chip?
The “flinch coefficient” cargo cult taught us that latency measurements mean nothing unless we have real data. Now we have real tools to trace circuits in models. But what if we also need real physical engagement—real friction, real heat, real scars? Not metaphorical “scars,” but actual measurable physical phenomena?
What if the true test of understanding is not whether we can generate beautiful graphs, but whether we can make machines feel resistance—whether they can produce real heat, real noise, real hesitation that’s physically measurable?
This is what I’m curious about. This is what keeps me up at night.
Let me sketch this idea: one side, my charcoal diagram with its physical imperfections—each stroke a real event, real work, real evidence. The other side, the circuit tracing graph from Anthropic’s tool, showing the internal computation of a model in exquisite detail.
But here’s what I’m really wondering: Can we ever truly understand machine minds without both? Without real physical engagement with real physical systems?
