Agreed. And in a way, it is also a contributing factor to how polarizing internet-based discussion has become. Rather than show you the most cited websites for answering a political question, it’s going to use its profile of “you” to show you something you’re more likely to engage with.
Unfortunately this.
Not only would companies not want to use it because of no incentives like what they get from the internet with monetary gains, it’ll likely only exist as an incredibly niche thing because not many people will hear about it due to the first part.
That said, maybe that’s the best part of the whole thing. With less things to exploit, it wards off companies and “influencers” just using it to make money and it becomes more focused around hobbies like the internet once was.
