I totally agree.

IMO the notion of merit is an illusion. It hides the assumption that people can be ranked and compared, but do we truly want to live in such a society?

Also, is that even feasible?

It's impossible to objectively compare humans of similar "skill level". For example, think of Plato and Aristotle, they have been dead for thousands of years and their work has been studied but millions of not billions of people, yet people still argue who was the best philosopher of the two. How can we have a meritocracy if we cannot evaluate merit? You may be able to distinguish experts from beginners for a certain skill, but, when considering roles of influence/power, there are multiple skills and attributes to be considered, and the same principle applies.

It's easier to cheat a merit metric than to evaluate it. Any algorithm that makes a decision based on merit will need to either evaluate or compare it. Both are going to depend on the presence of absence of features that once known to a cheater they will be able to fake them. That makes evaluation and cheating a competing game, where the evaluator and the cheater contiously adapt to one another, with the cheater being much able to adapt much faster.

Any meritocracy will have to be open about it's evaluation process. If it's not participants with merit cannot know how to demonstrate it and the process is prune to corruption.

Personally, I believe making decisions based on trust is much better. It's hard to build trust and it cannot be cheated. Of course, cheater may try to influence decision makers with bribes or blackmail. But, once this is found trust is destroyed and they get rejected.
