But how much cheaper is it to learn a profitable skill? In the 1980s I’d have had a much harder time learning to code. I learned essentially for free. A traditional, hand holding education is more expensive, but information is virtually free.
The further you get from that, the worse teacher the internet is. There are many skills I've learned which are hard to find information about online, and a few which don't seem to exist on the internet at all.
Not every profession has someone who took the time to sit down and put all their knowledge on the internet for free. Some fields are just getting around to putting it in books.
Do you have any examples? Sounds like an opportunity.
There's plenty of content created by people who don't really know what they're doing, or who only have a rudimentary understanding.
I guess that's true of all education, but it feels like a bigger problem with free online content.

Of course I didn't learn the programming discipline until college many years later, and it shows in my early code.
