A few weeks ago, I saw a tweet that said “Writing code isn’t the problem. That statement nicely summarizes what makes software development difficult. Anyone who works in programming has seen the source code for some project evolve from something short, sweet, and clean to a seething mass of bits. Controlling complexity is.”

GitHub Copilot (based on a model named Codex , which is derived from GPT-3) generates code in a number of programming languages, based on comments that the user writes. Going in the other direction, GPT-3 has proven to be surprisingly good at explaining code. But it’s obvious where this is trending. But I don’t know if that’s true.

First, the behavior of an AI application depends on a model , which is built from source code and training data. A model isn’t source code, and it isn’t data; it’s an artifact built from the two. This means that, to have a history of how an application was developed, you have to look at more than the source code.

The same mindset should also be applied to architecture; involve the whole team and challenge the small details.

It's a given that we must design a system, including a local software architecture, that actually runs, that is "solid." The architect is hopefully not concerned with low-level details of the code itself inside one system but is more focused on where data center boundaries are crossed, where system component boundaries are crossed.
