False. Nobody does this. They hold pieces of context and summaries in their head. Nobody on earth can memorize an entire code base. This is ludicrous.
When you read a function to know what it does then you move on to another function do you have the entire 100 line function perfectly memorized? No. You memorize a summary of the intent of the function when reading code. An LLM can be set up to do the same rather than keep all 100 lines of code as context.
Do you think when you ask the other person for more context he’s going to spit out what he wrote line by line. Not even he likely will remember everything he wrote.
You think anyone memorized Linux? You know how many lines of code is in the Linux source code. Are you trolling?
If I need more, there is git, tickets, I can ask the person who wrote the code.
I do have read your comment, don't make snarky comments.
