> I don't think Julia really solves any problems that aren't already solved by Python.

But isn't the whole point of this article that Matlab is more readable than Python (i.e. solves the readability problem)? The Matlab and Julia code for the provided example are equivalent[1]: which means Julia has more readable math than Python.

[1]: Technically, the article's code will not work in Julia because Julia gives semantic meaning to commas in brackets, while Matlab does not. It is perfectly valid to use spaces as separators in Matlab, meaning that the following Julia code is also valid Matlab which is equivalent to the Matlab code block provided in the article.

    X = [ 1 2 3 ];
    Y = [ 1 2 3;
          4 5 6;
          7 8 9 ];
    Z = Y * X';
    W = [ Z Z ];

This snippet is also cleaner than one in article and more in spirit. Also the image next to whiteboard has a no-commas example.
