A human would give you the same solution for the same reason. No dev would deeply ponder the meaning of “cout” if told to print something. It’s so simple it’s almost muscle memory.

Hell, there are probably non-NN autocomplete systems that could successfully do that.

GPT can do more than that though. You can have a conversation with it about what you’re trying to achieve and what the requirements should be and then you can tell it to write code on the basis of that natural language conversation. You can then discuss the code with it, make suggestions or ask for them.

People who claim that it’s “just” looking up the answer in its training data seriously have no idea what they’re talking about.
