A very good point. Most things one could learn at a university are also printed right there for anyone to see in a textbook--yet people STILL go to university.
I wonder why CTE purveyors haven't taken that route (since it hasn't seemed to harm universities). But no, CTE contains mystical secrets that can't be divulged on, for example, discussion forums.
I guess you're not aware that prestigious universities are now putting videos of many of their courses online for anyone to view--free of charge, OR that most universities allow "auditing" of many of their classes by the general public. Most university classes don't "take attendance" so ANYBODY could be in them, and nobody would know (I was once involved as a teaching assistant for a HIGH LEVEL university biology course, understandable only by relative "experts," where the best student in the class was someone who more or less just "walked in off the street." I was a bit pissed off, after taking the effort to grade her exams, when I discovered she wasn't on the official list of students!)
Here's the first class of a
year long course in physics from the famous physicist Leonard Susskind.
Here's a great one
from MIT on solid state chemistry.
Or maybe you'd like to learn about
circuits and electronics from MIT?
BTW, Stanford and MIT are PRIVATE universities--not state sponsored. They GIVE THIS STUFF AWAY, yet people scramble and compete by the tens of thousands to go there and pay for it ANYWAY.
Hey, maybe you can go back to school and actually LEARN something? I'll tell you one thing for sure, if Stanford or MIT ever decides to have a class on POOL I'll definitely be watching it!
