I fail to see how that last sentence makes it sound like a photoshop filter. Do you mean if you can express it as an algorithm it cannot be compared to human learning?

What if we can reduce human learning to making predictions based on training data? Then it's not human learning anymore but more like a photoshop filter?

"Everyone knows that the term machine learning doesn't actually have anything to do with human learning, right?" Do you have sources for that? They're not equal but I see a lot of parallels.
