Wired wrote an article in 2017 [1] on whether it's possible/probable to do that. Technology has evolved a lot since then, so it's a lot more feasible, but the article describes how far metadata alone can go.
For example, let's say an ad network knows your and your friends' location, and knows you've met because you've been close together frequently, or are using the same wifi network. You talk about perfumes, then later one of them looks up perfumes on their phone. Google would usually have access to this much metadata, and will likely serve you perfume ads because of your friend who later looked it up.
This doesn't directly answer your question though. The answer would be - it's possible, but a lot is possible without that.
This sounds plausible. But otherwise, there are "tournaments" like the TCEC which is for bots only and the way it works is, the bots are adjusted to play a specific opening and they're on their own after the Nth move.
Stockfish has been dominant for a long time. And a later version of Stockfish would outperform an earlier version given the same time control.
It's pretty slick looking which is worth something to me. Not $750, but something. But even though some of the UX choices of Jellyfin didn't make sense to me, it's an amazing piece of software, so I'm sticking with that, and using Wholphin [1] as a frontend.
Coolify's website [1] explains it better.
But for example, you can call a webhook once new resources have been created, so Coolify can push them to your CDN.
