Technology

There's two points of consideration here, let's see if I can make my point without a wall of text, I'm prone to those...

1. Anonimity: the fact that where you connect cannot know who exactly you are. This should be straightforward, anonimity should not be taken away, it is a core part of the internet in my opinion. It's extremely important that we can express ourselves freely without fear of being persecuted. Despite the negative sides that it has, as those with ill intent will be harder to find (but not impossible). In this the common quote attributed to Franklin applies well in my opinion: Those who sacrifice liberty for security deserve neither.

2. Proof of personhood: basically the difficult task of making sure that the other end of an internet connection has a real person, and together with that, proof that it is different than others, the ability to know you are you and not someone else.

This is incredibly interesting as a technical problem to be solved, and I do agree with you that the internet as we know it is at risk if we don't solve it properly. It is specially hard to solve if you try to guarantee anonimity (like I believe it should be).

The wikipedia has an article about it that I think gives a good idea about the topic: https://en.wikipedia.org/wiki/Proof_of_personhood

Personally I have been quite carefully interested into the whole World ID solution, using a device called orb with open specifications that captures some data from your iris that should be unique per person, storing only an encrypted piece of information in a blockchain and on your device locally so that you can use it to identify yourself as a real unique person and only once, but wherever you use it, cannot know anything about you except that. There's a lot of possible criticism to such a system, but insofar as I have checked and can understand, it seems like a legit solution. But I leave here the link for anyone interested enough to check it themselves: https://world.org/world-id
