My reading of the article, was that the author seems to be in search of a new paradigm, that moves beyond what he sees as the limitations of "fp-like" languages as they exist today. His point appears to be that Zig provides the benefits of "fp-like" languages that exist today, while avoiding at least some of the downsides.
And he does admit you may have to squint, to appreciate the fp capabilities provided by Zig.
