Unlearning OOP does not necessarily involve forgetting abstraction and the concept of an object. "Unlearning OOP" involves freeing yourself from the notion that all programming should be designed as an object hierarchy.
There is/was a tendency in object-oriented programming to consider that it is the only way Real Software™ is made. You tend to focus more on the architecture of your system than its actual features.
Notice the prerequisite to unlearning something is learning it first. I don't think anyone proposes that the concept of an object is useless.
