I've noticed that HN can attract some of the most extreme people I've ever seen, and I suppose there is precedent in the tech world when I'm reminded of the story of Stallman not using a browser but instead sending webpages to his email where he then reads the content. It's literally nonsensical for 99.9999% of the population and I've read similar absurd things on HN as well.
This person not using LLMs is fine, I understand the argument like you said, but the double down on not using search engines either makes me not take anything they say seriously. Not to be too crass but it reminds me of this situation on the nature of arguing on the internet [0].
