which brings to mind the old William F. Buckley Jr., who famously remarked that he would rather be governed by the first 2,000 names in the Boston telephone directory than by the faculty of Harvard University.
But the idea of randomly selecting leaders as a leveling distribution is as old as Athens. We still practice it in Jury selection in much of the world.
So this experiment in Belgrade might be worth watching and it wouldn't surprise me at all if they outperform previous and regional governments.

You comment is a bit unclear as to its point.
These new batch of people are not randomly selected; they are thought of as more suitable to rule due to their being academics and scientific/technical experts, rather than lifetime politicians. Same as the old politicians who were cut from a certain cloth.
The cloth is now different, but a cloth it remains.
