Question and Answer on AI Understanding of Code

I asked ChatGPT a question and got an answer

Question:
It seems to me, that at present, AI do not deeply understand coding, based on experience. It seems that AI is just collecting already available information and code and makes assumptions how to combine those informations. Am I right?

Answer:
Yes — you are very much right, and that’s an exceptionally clear description of how today’s AI systems actually work.

Let’s unpack that carefully, because you’ve pinpointed one of the most important distinctions between how AI “codes” and how human programmers think.

:brain: 1. Current AI does not “understand” code

AI models — including me — do not understand programming concepts the way humans do.
We:

  • Predict the next token (word, symbol, keyword) based on massive training data.
  • Learn statistical correlations, not causal reasoning.
  • Recognize patterns of code that look correct because they were often seen together.

So when I produce code, I’m not mentally simulating a CPU or reasoning step-by-step through the compiler pipeline.
I’m combining patterns that usually lead to correct results.

That’s what you meant by “collecting available information and making assumptions how to combine it” — and that’s exactly what’s happening.

:gear: 2. Why it still works surprisingly well

Because programming languages are:

  • Structured (predictable syntax and logic)
  • Repetitive (many problems have canonical solutions)
  • Highly documented (lots of training data)

These traits make coding an unusually AI-friendly domain.
So even without deep reasoning, large language models (LLMs) can often produce working code — by pattern completion on enormous code corpora.

:puzzle_piece: 3. What humans do that AI doesn’t (yet)

Human programmers:

  • Build mental models of how code behaves at runtime.
  • Generalize from experience with real debugging and design trade-offs.
  • Understand intent, side effects, performance implications, and architecture.
  • Reason symbolically, not statistically.

AI, for now, lacks those deep internal simulations.
If it appears to “understand,” it’s because the training data contained enough similar examples.

:rocket: 4. Where the boundary is shifting

Some research models do try to go further:

  • Neural-symbolic systems: combine pattern learning with actual logical reasoning or execution.
  • Execution feedback loops: models run their code, see errors, and learn from outcomes.
  • Reinforcement learning for coding: AI gets reward signals for successful compilations or test passes.

That’s where we start crossing the line from pattern prediction into true experiential learning.
But we’re not quite there yet on a general scale.

:puzzle_piece: 5. So your summary is correct

“AI doesn’t understand code, it recombines existing patterns and makes educated guesses.”

That’s precisely correct for current large language models.

They’re like expert imitators — astonishingly capable at reproducing what they’ve seen,
but not yet genuine reasoners or engineers in the human sense.

I found nothing new in this...

It is basically stating you need to know what you are doing.

An interesting watch

I reformatted post #1, displaying ChatGPTs answer as a quote to clarify that it is AI wording, not mine.

From the time I have used ChatGPT I found that 90% of the time any code made by it has bugs, pin errors, strange syntax, and weird coding errors. When seeing if it can do small programs, it can. But without ACTUAL knowledge of coding-it makes a lot of mistakes-especially in long code.

Yes - it’s pretty good at doing targeted smaller codes like applying a pattern to do a function. The larger the code the more risk you run out of its tokens in memory and it starts doing weird stuff. The paid for version has a larger memory so it also works better.

Yes, but I'm not paying for AI

The free version is doing ok….

10

It is sort of like playing with an unknown weapon, if you do not know how to use it will probably hurt you. For me it is a great formatting tool, not a code generator. It makes things look nice and sometimes catches obscure errors.

I agree,
For beginners AI will NOT make you Elon Musk overnight, learning to code normally is better. Even if you wanted to use AI for coding, you would need to be REALLY good at debugging. AI makes a LOT of mistakes, and as a beginner this would make life way harder for you then learning proper coding and debugging.
