Since JJ has technically git compat, I think there's 2 things needed for it to take off

1. A good vscode extension (there's two so-so ones that I'm not sure are being updated) 2. LLM knowledge. I ask gpt-5 about doing something in jj the other day, it didn't even recognize it at first. When I reminded it it was a vcs it hallucinated half the commands. I ended up figuring it out myself from the docs

Using VC commands an LLM generates for you sounds like a pretty terrible idea anyway. What if they delete your data? Why not spend 5 minutes searching for information written by a human?

I'm not running them blindly and I do always ask the llm to explain the command since the end goal is not to have the llm do the work but rather for me to learn jj.

+ any good tool will not let you run destructive commands without confirmation unless it's with some force flag and I have enough computer knowledge to not use force flags blindly.

+ "information written by a human" can be unreliable too.
