The blind leading the blind? Most conferences have lineups of well respected people involved in an ecosystem. From language authors to open source maintainers and such.
It seems you don't seem to understand the purpose of conferences and blogs. These talks are not to showcase the best quality production code that can pass any review process. They are to showcase new developments and new approaches to do things in a specific field. It's meant for people already in the field (or starting to get into it) trying to learn more.
If such talks have high quality production code in slides the message would get easily buried under stuff that isn't important for conveying the message they are trying to say.
