Laurence Moroney: build each AI pipeline component by hand once, then let AI write it
lmoroney · x · 2026-10-26
A learner who skipped most coding in a RAG course asked whether it's still worth implementing things from scratch when AI can write the code. Laurence Moroney's take: build each core piece by hand once — chunking, embedding calls, similarity search, prompt assembly — even if rough, then let AI write it as fast as you like. Doing it once builds the mental model needed to review generated code, notice junk retrieval results, and debug at midnight. His challenge: pick a course project you skimmed, rebuild only the retrieval step by hand this week, and compare with the generated version.
