I have a hard time with this one. Technical people understand a skill and uploading a skill. If a non-technical person learns about skills it is likely through a trusted person who is teaching them about them and will tell them how to make their own skills.
As far as I know, repositories for skills are found in technical corners of the internet.
I could understand a potential phish as a way to make this happen, but the crossover between embrace AI person and falls for “download this file” phishes is pretty narrow IMO.
