Call me old fashioned and stuck in C style syntax but I can't imagine anyone describing this as beautiful art.

When the junior programmers start saying "Turing complete" or the academics build a DSL in Julia that uses RegEx to parse Logic Symbols and stuffs the result in variables that use ancient characters that don't appear on your keyboard, it's a sure sign of imminent progress. Bonus if the PhD with nine years of schooling and five months of PHP experience at Facebook starts using emoji in commit messages.

I see it as beautiful the same way Galadriel would be beautiful as the Dark Queen. Utterly captivating and powerful, and yet something that should never be.

Great to hear. So what is it?

Not op, but I assume it means that there's rank polymorphism (i.e. data can be of arbitrary dimensions, and there's support for things like functions working on both N-dimensions, without having to specify n, or maybe setting constraints on n), and that the polymorphism can be used on the programmer side (so it's not limited to just a handful of language builtins) through the oop equivalent of subclasses and interfaces.

The programmer can define functions that operate on matrices without having to be explicit about the number of dimensions and possibly (types of data, size of data, or length).
Example 1: A function that can take as input a 4x2x8 matrix or a 3x7 matrix.
Example 2: A function that can take as input a 4x2x8 matrix and a 3x7 matrix and output a third matrix.

game math libraries often have this (and glsl gpu shader language), like "2 * vec3(1,2,3)" results in "vec3(2,4,6)"
There are other cases like adding vectors to matrices and so on, but in the end this logic is defined in some custom add operator overload on a class or object in the language.
(I had no idea what it meant either until i searched for examples..)

Dlang does not has rank polymorphism and it handle array just fine with crazy speed in both compilation and execution.
It can be faster than Fortran based library that is still being used by Matlab, Rust and Julia [1].
It will be interesting to compare Mojo moblas BLAS library with GLAS library performance in D.
[1] Numeric age for D: Mir GLAS is faster than OpenBLAS and Eigen (2016):
If I understand correctly what is meant by rank polymorphism, it is not just about speed, but about ergonomics.
Taking examples I am familiar w/, it is key that you can add a scalar 1 to a rank 2 array in numpy/matllab without having to explicitly create a rank 2 array of 1s, and numpy somehow generalizes that (broadcasting). I understand other array programming languages have more advanced/generic versions of broadcasting, but I am not super familiar w/ them
