I will definitely think about it. Totally agree that this would be very valuable. And some sort of solution should probably be doable

I think to get it done on every single video though, it needs to somehow be a part of the infrastructure, similar to how youtube does it - there, every video uploaded is automatically transcribed. Now, imagine if automatic transcription of any video uploaded to the spk network was incentivized and delegated to nodes... I'm probably thinking a bit far ahead, but this would be ideal to aim for
