First off, in actually using Zola or Hugo, there really is minimal difference in syntax, and I really have to squint to see whether there is stylistic input from their host languages.

Second, people should use the tools they want to to get the job done. If they already know Hugo, and they want to create a blog, it's fine that they use Hugo.

Finally, the bigger decision that the blogger seems to be trying to make is to avoid LLMs in writing, which I admire, and IMO is the far more important technology choice in making their blog.
