I don't find this dismissal persuasive. If I understand you're point, you are arguing that without perfect truth, no partial solution has any value.

If that is indeed your argument, it is remarkably similar to the argument "Perfect security is impossible, this system is worthless." I think it is demonstrably obvious that there is a related parameter in both cases, which is the cost of overcoming the system is greater than the gain from overcoming said system.

As an example of how that argument fails in practice, consider textbooks. When I was working on this problem full time the organization had a relationship with a major publisher of textbooks. Consider the system which can construct an ontology and knowledge graph based on the contents of a text book. It may not be 'true' in the Aristotle sense, but it is an effective tool for evaluating whether or not a paper or essay correlates that ontology and knowledge graph or doesn't. In such a system there is value in evaluating the extent with which the knowledge in the textbook has been communicated to the person writing the essay.

Being able to automate the analysis has other benefits as well which extend beyond flagging documents which disagree a previous established canon.
