I think Skills could turn into something like open source libraries: standardized solutions to common problems, often written by experts.
Imagine having Skills available that implements authentication systems, multi-tenancy, etc.. in your codebase without having to know all the details about how to do this securely and correctly. This would probably boost code quality a lot and prevent insecure/buggy vibe coded products.
And then you make a global index of those skills available to models, where they can search for an appropriate skill on demand, then download and use them automatically.
A lot of the things we want continuous learning for can actually be provided by the ability to obtain skills on the fly.
Reminds me of that helicopter scene from The Martix movie where Trinity loaded relevant instruction on helicopter piloting on demand :)
