Anthony Morris, As I recall, talked about the popular view in the 1970s that kids would never grow up in this system. He omitted to mention that this had been printed in the literature, instead poured scorn on those that said it.
His theme was on keeping going no matter what or how long they have been doing.
I did not see it as disputing that the end was near.
I wish I could find the thread that discussed it but I cannot.
