As someone that studied on Universities that prefer OOP first approach, I would disagree.

Design skills can be only learned through experience. Understanding what abstraction to apply is something you would learn after many "failed surgeries". You can only learn this on the job and by reading a lot of code.

Writing efficient software is impossible without understanding machine. Without knowing how things are represented in memory or how compilers/OS works you will never write good software. You will end people that do not understand how event loop in node.js work or write thread safe Java.

Just ask few practical question about Promises, Heap, GC, Threads and you will see blank faces from the same people that just white-boarded DFS.
