I work in a field where most of my customers are self-taught, often (but not always) degrees in other fields. I can only use my experience as a reference, ymmv.

What ive noticed is that people have different strategies to learning. Most adopt a "just in time" approach. They learn only enough to complete the task at hand. There is very little curiosity in the bigger picture, or the fundamentals.

This is the opposite to the formal approach, which grounds the learning in theory.

can people learn the fundamentals in a self-taught way? Obviously yes. Do most people learn this way? Id suggest not.

The contrast is to students at college who are always asking "hey am I learning this? When will I use this?" It's not always obvious where they become important.

In my own career I was able to leverage my fundamentals training and translate that into value to those who just want to complete a task.
