In the 21st century, time has long passed for institutions to begin leveraging such platforms. They failed to seize the opportunity. This might end up being a good outcome, however, as citizens are now afforded the opportunity for course correction in the political power dynamic and can bring about true legitimacy, rather than the semblance we have of it today (assuming there’s even a semblance of it left at all).
In the 21st century, the only thing it is “high time” for is for the citizens to begin leveraging such platforms. What does this mean? It means that in the 21st century, you don’t find the experts, the experts find you! It means that in the 21st century, citizens define the need, the problem, the solution (pro tip: citizens define it all, they hold all the power, hold all the keys to all the doors) and institutions rightly follow the lead inherent in the authority of the citizenry. This is self-evident.
The day citizens realize that freedom is the essential prerequisite to get to a better world, will be the day citizens working within institutions realize that imposing external control on others is no way at all to get to a better world…in fact it is the only way to make the world a worse place.
tl;dr Try accepting the freedom of individuals and you might be surprised at how easy it suddenly becomes for expertise to find its desired place and role in the world. Under the conditions of freedom, the elusive “match” you are looking for happens all on its own. However, imposing conditions of control over others by seeking expertise to solve the problems you have controlled and defined to be as such leads us to where we are today.
