| > I'm not sure how you get from "LLMs work in mysterious ways" to "So we need more discipline" to "everything is fine." Are you referring to this part: > I am not worried, at least in the near term, about AI creating massive, discontinuous returns on investment in the absence of engineering discipline. (Many will try, and it will be entertaining to watch.) She's saying, "the amazing thing about LLMs isn't that they generate lots of code fast, so don't worry about people using LLMs for that taking over the industry" She's making two points: 1. Before infra-as-code, people would be afraid to touch parts of production due to lost knowledge about how and why it got that way. Now that we have infra-as-code, you aren't allowed to change infra the old way (ad-hoc changes via dashboard/CLI), even if doing so would be faster and easier. Experienced SREs were required to abandon lots of their old skills with CLIs and dashboards and start working in a completely new way, because the knowledge captured in a terraform repo's commit history is so valuable. 2. In the past, the way code got written was through people making changes in ways that are specific to their current knowledge, the org's current problems, the current users, etc, some or all of which is not written down. Eventually, everyone is afraid to change certain things because they don't know or remember all the considerations that went into them (not just afraid to touch parts of the code, but afraid to delete seemingly-unused features, or migrate the schema, or whatever). Charity is saying that problem 2 is a hidden/lost-knowledge problem like problem 1, and the amazing thing about LLMs is you have to write down all the knowledge you want them to have, which may lead to a better solution to the "lost knowledge" problem in software development, which would be so valuable that experienced software engineers have to abandon lots of old skills and start using it. (Not only writing down all the knowledge you want the LLM to have, since they're flaky enough to ignore instructions and miss implications sometimes, but building test suites and tools and so on that adequately guide their solution. This is the "more discipline" she's referring to.) |
