Cybernetics originated in engineering and mathematics so it makes sense that it would be concerned with control as we tend to explicitly limit and constrain complexity in order to control and predict our systems - ML being the first notable counter-example. Systems theory started out in biology and ecosystems so AFAIK it never held that complex systems could be either fully known (total knowledge of the state), or truly controlled.
Daniel Schmachtenberger is also working in the field of sensemaking so his talks and writing may be of interest to you - https://civilizationemerging.com/about/ (& lots of talks on YouTube).
