Knowledge is not absolute value
Let's consider socioeconomic content:
There is no pure socioeconomic type we are living in, but one or a few types may rule others.
Knowledge was, is and will be with us, but it isn't absolute value, especially if you think that knowledge is always positive (knowledge society, economy, etc.). All depends on the limitations in which people create, consider and use knowledge - is it really understandable, feasible?
The limitations aren't external to knowledge because there is no life without limitations.
And any warfare is an indicator of lacking knowledge in the true (natural) limitations.
