A lot of things of value are very hard to measure.
X degree influences can be very hard to measure.
You may hit your target metric, but secondary effects may be making the whole system worse.
Ideally you could A/B a parallel universe to isolate your specifc change, but that is challenging.
Alternatively, if there was no Google or Google like company, we would likely be much further along in tech, and have better functioning democracies. They have limited innovation in maps and search products. They rely on being big to be competitive. Their products are pretty poor given their engineering team size. Digital advertising: they bought their way into a quasi monopoly, siphoning dollars from people that actually create things.
I like this - as a fan of democracy.
Democracy costs, I think it’s OK that it takes a bit of time, more representatives, more votes is OK.
More civic engagement is a positive. Hearing the viewpoints of your neighbour is positive.
A really interesting dynamic, is that you would be creating a strong pipeline of leaders/representatives developing bottom up.
