It wasnt a criticism of you, it was like if the most experienced 
and talented developers are struggling to make sense of it how 
can the average programmer (me) ever hope to use it correctly.

It just seems that whenever a DIP1000/safe thread comes up nobody 
really understands it.

Like it's the exact antithesis of "easy to use correctly"
