Whats the workflow for writing code like the app mentioned with chat? My experience was like the authors, its a massive environment set up, plus even small projects have 10s of files. How does the model keep all that in context plus changes. How do you start a new session? I checked some small cpp project and the code alone is 168,000 words, so thats already larger then the gpt4 context, that doesn't even include iteration and chat history. IDK where you would even get started. Also, dont really see the comparison between programming and chess. In chess you can still compete to be the best human chess player. Coding or working in corporate america doesnt really have that.
