"There's no learning curve" just means this guy didn't get very far up, which is definitely backed up by thinking that Copilot and other tools are all basically the same.
Basically, they are the same, they are all LLMs. They all have similar limitations. They all produce "hallucinations". They can also sometimes be useful. And they are all way overhyped.
