I think the difference between the first and second is whether you have a deep understanding of how high level languages translate into hardware operations. If you're a novice how that translation works might as well be magic.

The second panel understands how that translation exactly happens and then it absolutely makes sense.

The third one is the next step where you have an deep understanding how the underlying physical phenomen makes computers work, and again that might as well be magic because explaining it is like explaining magic.
