ah yes, AAI (Artificial-AI) AKA I (Intelligence), or "Crowdsourcing" if you're looking to use an older buzzword. I do think there's a few models trained on sponsorblock already, but they're not great.
...which will be countered by AI-enabled midroll ad generation. A neural network that splices two video clips together must already be a thing, right? The advertisers would probably want this even without adblockers, since everyone already has an adblocker in their mind called 'inattentional blindness'. Using AI to subtly segue into the ad rather than cutting would stop some portion of users from tabbing out, checking their phones or just going AFK during ad breaks.
