Why? We have xlsx for the office crowd and arrow for the HPC crowd. In no universe does anyone actually have to invent another tabular data format using delimiters.
Neither are a universal replacements for CSV. They're not even text formats (well, technically xlsx is if you expect the XML from the zip, but practically: no really.). The article already explains why, as the title says, "CSV is still king": it's widely used, it's simple, it's used all over the place, it's universal, it's human-readable-y.
