    I'm really struggling to see how to make architectural decisions with an agent. It's great when you're at a total loss for ideas, but when you already have some of the pieces it ultimately wants to drive all of the thinking and takes over. Then it just feels like you're deferring your experienced judgement. I've seen colleagues lose the ability to reason any more without asking the agent to do it for them, because they inherently don't see the point if the agent is going to end up doing the whole piece (and probably auditing/overruling anything they came up with on their own).

      Why would you care about architecture? It was an issue when humans were writing code so architecture mattered in the sense that you needed a sweet spot between current requirements and future extensions.

      The agent can rewrite half your codebase in one day, so architecture stops mattering for the most part.

        Abstractions. They make it easier for a human to understand. We need abstractions to fit systems into our working memory. Agents dont.

          Agents don’t have infinite working memory…

          LLMs benefit from abstractions for the same reasons that humans do. More information in the same amount of text. Fewer working parts to juggle so fewer ways to make mistakes.

            They have more working memory than we do. Not that abstraction won't help, but it is not why they are created.
