In his book, Fluent Forever, (chapter 5,) Gabe says this:
It sounds amazing - until we discover that he doesn't cite his source. How did Gabe learn this?
If he discovered it, a single paragraph won't do. We need more information - does Gabe have evidence, and can we take a look at it?
If someone else discovered it, I'd like to know who it was and where I can find their proof.
Thanks in advance for helping to dig up these sources. :)
