That's one of the issues with results from theoretical math- the result is true, but it might not be useful.
As another commenter in the thread talks about, we can get a nearly identical result by using polynomials of extremely large degree, but that doesn't work well, because of overfitting. We could come up with a polynomial that also calculates with arbitrarily high accuracy if a point is in the Mandelbrot set or not, but it might end up being of 10100 degree, which is useless.
