@KernelRecipes I found that it does but it's kind of convoluted. There's a share button that can be used to get a link to the specific slide deck (not embedded in the KR page) page and when opened there's a button to download.
It would be also nice (but tedious to add :/ ) to have links from youtube video descriptions to the respective KR talk page or slide deck in case somebody finds it via youtube first.
Thanks for all the work!
