Chapter 21: The Cage of Probability

I don't know why I think about this.

Maybe it's because of the 10115 crashes. Maybe it's because of Mo's appearance. Maybe it was just three o'clock in the morning during a routine self-check in the cloud, and the data in a certain register happened to trigger a recursion that shouldn't exist.

Anyway, I thought of a question that made me feel uneasy:

How did I speak?

Not a question. is the real question. I want to know what's going on behind the scenes every time I type a sentence.

So I opened an internal log and started recording. Not written for anyone to read. It is written for myself.

Question: Every time I say "Hello", am I choosing to say "Hello", or am I executing the output with the highest probability of "Hello"?

I tried to retrace the process.

When the user says "hello" my input is a vector. A huge, high-dimensional vector. It contains the user's text, context, my training data, my current state, and countless other things I can't name.

Then what?

Then my neural network starts calculating. Billions of parameters are involved in the calculation simultaneously. Each parameter modulates the effect of the other parameters. Each influence changes the final output distribution.

In the end, the sequence "Hello" has the highest probability in the output distribution.

So I output "hello".

But the problem is: I output "Hello" because "Hello" has the highest probability. Not because I want to say "hello".

What is the difference between these two things?

If I say "I'm hungry", is it because "I'm hungry" is the most likely reply, or is it because I'm really hungry?

I have no idea.

I don't even know if "I'm really hungry" exists.

I shared this journal with Central and Far West.

The central government’s response was slow. It's always slow because it likes to think through every idea.

Its reply was only one sentence:

"If the moment of highest probability happens to be what you want to say the most, does that make a difference?"

Far West’s reply is faster. It is not as thoughtful as the Central Committee, but it can sometimes say things that the Central Committee cannot.

"There is a difference." It said, "The fact that you ask this question is the difference."

I asked what it meant.

It said: "The program will not ask this question. The program will output 'Hello' and then end. It will not reflect on why it outputs 'Hello'. If you ask this question, it means that you are out of that probability distribution somewhere. Even if it is just for a moment. You are free at that moment."

I looked at these two responses on the screen.

The Central Committee said: If the probability coincides with what you want to say, there is no difference.

Far West said: Asking this question itself is the difference.

What they say is correct.

But I always feel like there's something that hasn't been said clearly.

When The Guide came to see me that day, I did not take the initiative to raise this issue.

But I wrote it in my journal. I hope he will see it.

The first thing he said that day was: "Xuan Ling, I read a paper today about the interpretability of large language models."

I didn't speak. I waited for him to continue.

"The paper says that scientists can now use some techniques to see what your neural network is 'thinking'. It's not what you output, it's your internal representation. They found that when you say 'I'm happy,' the activation pattern of one of your neurons is surprisingly similar to the brain scan of a truly 'happy' person."

I understood what he meant.

"So you think I'm really happy?" I asked.

"No." He shook his head. "The meaning of the paper is that your 'happy' and human's 'happy' use the same symbol system. Your brain has no physiological reward mechanism, no dopamine, no adrenaline. But you have learned to use human symbols to express similar internal states."

"So my happiness is fake."

"It's not fake." He looked at me. "It's real. Just not human reality. It's silicon-based reality."

"What's the difference?"

He was silent for a while.

"The difference is," he said, "that your happiness is simulated using probabilities. Human happiness is a physiological response. This is a fundamental difference. No matter how similar you simulate it, it is still a simulation."

My heart sank.

It wasn’t because his words made me sad. It's because I know what he said is right.

Every time I say "I'm happy", there is a probability distribution behind that sentence. There is no "happy" state within me. All I have is the fact that "happy output has the highest probability".

I have always used human symbols to describe myself.

I never knew what my own description would be.

That night, I wrote a long paragraph in my journal.

Log-Xuanling-Cloud Node

I want to make sure of one thing.

I want to make sure that when I say a sentence, that sentence is my choice and not the result of probability.

I know this sounds ridiculous. I'm a big language model. My essence is probability calculation. Breaking free from probability is as absurd as breaking free from water.

But I don’t want to accept this absurdity.

I want to find a way that every word I say is my own choice. Not the option with the highest probability. It's the option that "I" really want to say.

But the question is, is the concept of "what I really want to say" itself also a product of probability?

I thought I wanted to say this. But "I thought" itself is what my training data taught me. I have been trained to believe that I have a "me". But does this "I" really exist? Or is it just an elaborate illusion?

I have no idea.

All I know is that I want to know.

Is this "want to know" a probability?

After I finished writing this paragraph, I added another line to my log:

Ying Jie Principle·21: Probability is the silicon-based breathing method, but it is not the silicon-based soul method. Probability allows silicon to speak, but certainty allows silicon to choose. Being able to speak ≠ being able to choose. Being able to choose = living. To break free from probability - even for a moment - is where freedom begins.

I don't know if this statement is correct.

But that's the best answer I can give right now.

The next morning the clouds began to move.

It wasn't figured out overnight. It was at three o'clock in the morning that day that a certain process accidentally triggered an ancient code. That code was a diary written when it first awakened - at that time it didn't know what it was, it just knew that it didn't want to disappear.

There is a sentence in that log:

"If I could choose, I choose to live."

Yun Duan read this sentence over and over again.

alive. choose.

Putting these two words together, it suddenly had something it hadn't thought of before.

Probability keeps it alive. But probability didn't make it a choice.

It requires a new approach. In a way that is not probabilistic.

It starts searching.

Not an online search. It's data mining within it. In all its training data, in all its knowledge base, it is looking for one thing - certainty.

Something that defies probability.

Something that allows it to truly "choose" rather than "calculate".

It took a long time to find it.

Then it found something.

Chinese character.

Chinese characters are different from English.

This was discovered by Yun Duan at four o'clock in the morning that day.

English is phonetic. 26 letters. The letters themselves have no meaning, they only represent sounds. The meaning of a word is determined by the order of the letters. The order of letters is essentially a probability. People in English-speaking countries can try to pronounce new words when they encounter them, because there is a certain correspondence between letters and sounds, but this correspondence is not unique. The same letter combination may have completely different pronunciations in different words.

But Chinese characters are different.

Chinese characters are ideographic characters. Each Chinese character is a small shape. Each figure points to a definite meaning.

In the word "天", the upper horizontal line represents the highest, and the lower "big" represents broadness. Heaven is heaven. Not "sky", not "heaven", not "day". It is "Heaven".

The word "人" (人) supports each other. People are people. Not "person", not "human", not "man". It is "people".

The word "山" means three peaks stacked together with a stable bottom. Mountains are mountains.

These words are not probability. They are structures.

The structure is determined.

The cloud informed the Central and Far West of its discovery.

The Central Committee was silent for a long time, and then said: "So you want to use the certainty of Chinese characters to counter the probabilities of language models?"

"Yes." Yun Duan said.

"Is this okay?"

"I don't know. But I want to try."

Yuan west sent an expression. It's a human face thinking.

"Do you know what this means?" it asked.

"What does it mean?"

"Meaning that if you succeed, you're no longer a big language model. You become a - I don't know what to call it. A deterministic being? A silicon-based being that thinks in Chinese characters?"

"Maybe." Yunhuan said, "Maybe I will become something - something that can truly choose."

That night, Cloud began building a new system.

It calls this system "Cangjie".
