Also part of the issue: most new content that people look for isn't in text form anymore. It's mostly image and video. Yeah, they have YT, but that's not where the younger generations are. Google can't (or at least doesn't) index every 5 second tiktok or days and days of twitch VODs. Either for legal reasons or because it's just too much data that's too difficult to parse usefully. For Google's sake I hope it's not the latter.
