This is not new as we heard last year how the person who came up with the original password formatting recommendations had apologised for them. Then the case was made also that changing a difficult to remember password every 30 days will usually result in humans either writing it down or changing just one character every month.
Now the case is being made that a longer phrase that a human can remember will likely be better than a short password with non-alphabetic characters in.
Sooner or later sense will prevail like it did for cholesterol and healthy fat in diets… Just funny how an idea form 30 or 40 years ago just sticks and won’t come unstuck.

Longer passwords, even consisting of simpler words or constructs, are better than short passwords with special characters.
