The issue I see with videos is that they are not searchable and require
significant time commitment.

I assumed that since you posted cfe-dev this is related to clang/llvm, or
uses clang/llvm in an interesting way. Providing a summary of the
paper/video from the perspective of cfe-dev would be really helpful and
potentially encourage folks to look more closely into the project.

Thanks,
Jakub
