Telling people it's a tool to edit git repos makes it sound hackier than it is; not surprising they're nervous it'll break something.

Just tell them git makes mistakes easy, and jj makes them difficult.

I've tried that but it isn't very effective because usually if they are not a git wizard, they are already using some sort of git interface or GUI that prevents them from making catastrophic mistakes. So they don't see the appeal in relearning all their git knowledge and terminology.

Hence why I initially try to sell it as an addition to their toolbox, instead of as a replacement for their entire workflow.
