Although to be fair YouTube itself has started to defeat those - they put a little white dot in the timeline when the ad finishes.

I'm not sure how they do it but I think AI could pretty easily detect current ad transitions. Especially when combined with data about which bits of the video most people skip.

I think it'll lead to sponsorships being much more integrated into videos rather than a sponsorship segment. Or possibly people will switch to much shorter segments like LTT does.

I never really understood why they want long segments anyway. Shorter ones mean I'm much more likely to actually see it.
