A coding agent should make short work of that. However I'm a bit doubtful if the results would actually be meaningful.
I'm thinking that some of the LLM-isms are a bit more complex than just repeated phrases. It's often more that short, punchy writing style with quick setups and punchlines. But would be interesting nonetheless. I really think that some things (like "solving real problems" or "it's not"/"this isn't") would show up.
I'd expect to see a huge increase in "solving real problems" over the last months.
