saw a post recently in which the author wrote a reasonable sounding defense of the existence of data centers (not for AI processing, just in general) and a core component of their argument was that concentrated high volume data storage and processing was necessary for contemporary internet existence because the majority of data moved these days is video content (which is, compared to almost anything else, Really Big). and, for context, I'll be honest that I don't have any specific hate for data centers in general, although I'm viciously skeptical about the ways many of them are managed and operated compared to how they could be. but anyway what struck me about that argument later on the same day and I've been thinking about ever since is: what about ads? Internet ads have (as far as I can tell) almost exclusively abandoned banner and textual formats in favor of 15-120 second video spots. ignoring the question of whether they're conventionally or AI generated (and those are importent questions to ask, don't get me wrong!) what proportion of server traffic and data exchange on the public internet is dedicated to moving and displaying those video ads? To my knowledge there are no remaining streaming services that aren't ad-displaying (even if you can upcharge to bypass them), so if I'm watching for instance a 24-minute sorry I forgot it's the 2020s now 22-minute half hour episode of some show, how proportion of the data transfer demand and network traffic is prompted by my viewing is dedicated to the episode video file and what proportion is dedicated to auctioning, retrieving, and displaying the pre-episode, post-episode, and 1-to-3 mid-episode ad spots? What about if I'm, say, watching music videos (which are typically 3-5 minutes) on youtube, which have been pushed to have both pre and post video ads even at such a short length? assuming the argument that the public internet has principally become a video and multimedia access platform, how much data bloat would be immedtaely excised if we woke up tomorrow and all ads were magically banished? obviously I don't know the answer, but I do think it's a question worth asking
