You change a bit, ask questions, re-write the code to solve the problem
differently. Then go back and figure out what conceptual mistake was made
the first time through.
This is EXACTLY the same process you go through on a PC.

And embedded systems have them also, or you can write them.
But the primary reason I still disagree with you is that the Brick has so
few I/O that it simply isn't that complicated. I've taught 12 year olds in
a couple of owers how to use NCQ and get a bot rolling and reading a bump
sensor. They have more problems getting the driver registered in Windows
than understanding how to turn a motor on or read a switch. Now issues
related to higher level behaviour still stand; irrespective of the
platform.
