When I use LLM for coding tasks, it's like "hey please translate this YAML to structs and extract any repeated patterns to re-used variables". It's possible to do this transform with deterministic tools, but AI will do a fine job in 30s and it's trivial to test the new output is identical to the prompt input.
My high-level work is absolutely impossible to delegate to AI, but AI really helps with tedious or low-stakes incidental tasks. The other day I asked Claude Code to wire up some graphs and outlier analysis for some database benchmark result CSVs. Something conceptually easy, but takes a fair bit of time to figure out libraries and get everything hooked up unless you're already an expert at csv processing.
