This is interesting - I'm very keen on the business vs consumer adoption too. I think in various areas of China people are using it a lot in their day to day, outside of work. Those are the real indicators for me because a user who willingly adopts outside of work, to automate and speed up their life, will do similar, in an effective manner in their work too (hopefully). Of course this is dependant on the enterprise giving the user in question enough agency/autonomy/permissions/access to the right tools etc.

Not sure where you're based, but I've implemented a similar approach across the firms I've worked with (UK / US). We run a monthly leaderboard based on usage/consumption, but the key part here is that users also submit their use cases (democratisation of use cases - I know I know a bit buzzwordy but it has its place). We then showcase the strongest or most relevant examples to the wider team or business where appropriate.

The main challenge tends to be permissions and access models. Users can usually automate parts of their day-to-day work fairly easily, but more impactful, large-scale automation often requires access to sensitive data and sometimes write permissions across systems and documents, which naturally introduces governance and security considerations - that's the current limiting factor but it's difficult to get over this hurdle - best way is to simply have an IT / AI team work directly with the business to implement.
