Hey, I like my hours-long YouTube videos and would be remiss getting the Cliffs Notes. I wish Google would put those Shorts somewhere less in-your-face but sigh I know we live in a TikTok era.
I like long videos, too, but I could see this being useful to let it summarize a video beforehand so I can see if it's worth spending the time to watch it myself. Could also be good if you have a long video and you want the text transcription to use for reference later.
