This is true, and why I don't think we will ever have a true digital representation of "trust" The best we hope to build in highly specific contextual "trust" links
For example. I trust this guy as a dev, or I trust this guy on X topic
The issue is I don't think you can just build a generic "trust" rating app and call it a day. because the trust scores need to be updated periodically and you cant ask users to "review" their friends or trust scores. too much friction
If you let the perfect be the enemy of good, we'll never get anywhere. Approximated trust is better than the status quo IMO
its not a matter of making a good enough solution. its that if we are to find a good solution it has to be effortless for users to update their trust scores after the fact. even to the point where they don't even know they are doing it
The best example would be un-following someone because they posted something you don't like and never want to see. thats a form of updating your trust score but without the user even thinking about it
because it doesn't matter how fancy the UI in the app is. your never going to get a user to look at a list of users and remove the ones they don't trust anymore
