Should the vote of say a Biologist be worth the same in a matter of Biology then the vote of a non specialist in the field ?
Yes. It is the biologists task to inform those who must make the decision, same as it is now.
I do not have the faintest idea how such a system could be build, to be honest. I just know that we have the technological capacity for it.
Intuitively, I feel that restricting authority on some issues to those who have expertise is taking it in the wrong direction.
But how would we select which issues to vote on? Which decisions should be a public concern, and which ones should be left to the privacy of each individual? Personally, I think the fingers of the government (the Norwegian one) reach way too far, poking into matters that are strictly personal. When that happens, the democratic will becomes oppressive.
