Some people can learn independently. I fell in love with Science in 5th grade, my dyslexia seem to disappear, and the extra signal-processing power God cured me with was a joy, rational thinking! Applied to many fields of science I could find material on, the encyclopedia or my father had (as a commercial pilot when I was too young to remember, he had radio theory and aerodynamics books), much of the details required books on the science and physics I did not have access too - praise God for the unWoke sicken parts of Wikipedia and other sources on-line.

At 7th grade, computer programming was added. I learned Fortran, Cobol, Basic, eventually Pascal, and would have sucked-up others and some basic theories of OS, and such.

Back then, before WikiPedia or Wed-Site rabbit-hole chasing there was my father's Encyclopedia Brittanica, grab a random volume and open to a random page and turn pages until something interesting shows up.

If there is enough desire and good basic skills many people can learn independently of teachers. And it would not be difficult to have tax-paid mentors on-line to ask for details, especially if they paid to produce courses or to help direct people to good sources.

God Bless., Steve
