My own academic papers have a decent number of self references, too. But there is an enormous difference between referencing your own work, and telling the reader that the author is brilliant and those other people over there are stupid.
I am honestly not sure what you are saying. I never brought up Mandelbrot, only Taleb. (Although this is a curious example, since Taleb brings up Mandelbrot a lot.)
Do you think highly of Mandebrot? Clearly a deep thinker. Most of his writings are filled with his self references.
