Yes, more than raw speed, what impresses me is that the version of code in [1] is already a few times faster than the Mojo code - because that's pretty basic Julia code that anyone with a little Julia experience could write, and maintain easily.
The later versions with LoopVectorization require more specialized knowledge , and get into the "how can we tune this particular benchmark" territory for me (I don't know how to evaluate the Mojo code in this regard as yet, how 'obvious' it would be to an everyday Mojo developer). So [1] is a more impressive demonstration of how an average developer can write very performant code in Julia.
User lmiq articulates the sentiment well in a later comment in the OP thread:
> what I find more interesting here is that the reasoning and code type applies to any composite type of a similar structure, thus we can use that to optimize other code completely unrelated to calculations with complex numbers.
It matters less whether super-optimized code can be written in Julia for this particular case (though there's some value in that too), the more important and telling part to me is that the language has features and tools that can easily be adopted to a general class of problems like this.
