identity need not be just an "individual". It can be a group of individuals that agree to mutually sign data before dissemination.
Individuals, corporations and your toaster can create as many identities as necessary.
Right now we are all living seemingly schizoid lifestyle because we are forced to partition multiple selves into molds that are being provided to us.
The partitioning is necessary for organizing information. But the way it is partitioned should be flexible enough for the end user to have the ultimate say in what and how that information is curated. Currently, all we have are blackbox "algorithms." People are asking for transparency, thinking this will solve the problem. I think it will only lead to obfuscating the problem even more so.
Until the individual has unfettered control, we will always be playing this game.
I really wish conversations would wind back to towards discussing ideas tangential to the web of trust...
I think that problem was hard to solve for a reason. Being impossible not being one of them... but an easy position to sell if you feared the consequences ultimately lead to a loss of control.
