Just parachuting in to reflexively throw the "Luddite" label at someone lamenting the decline of a niche community they've enjoyed participating in and contributing to is certainly ... a choice.

Within the framework of your analogy, it's like responding to someone active in DIY maker groups suddenly dealing with an influx of influencers in meetups showing off Chinese junk from Etsy to post on Tiktok, and accusing them of being a Luddite blinded by their zealous hatred of mass production -- both strangely abrasive and also fairly nonsensical except as a "mass production supporter" social signifier.

Not to mention, in the article they specifically describe themselves as a heavy user of frontier models for security research ever since the release of Opus 4.5, calling them "useful within the field". In fact I don't see any actual criticism of AI/LLMs anywhere whether for security research, programming or anything else, except for making competitive CTFs no longer viable.

What does it take to avoid the "Luddite" brand? Using AI themselves and praising AI as useful (to the point of having a lopsided advantage over humans) isn't enough? Do they also need to say "I haven't written a line of code in 6 months/it's easily a 100x multiplier for my job" every time they mention it too?

The way I read the post is that the author is disappointed that the community is gone. The CTF was just a reason for a number of like-minded people to organize around an activity.

Indeed, in the real world, plenty of people organize to do formerly-skillful tasks together. I have not personally crafted a gear by hand, but I have built a house in a long-abandoned style with a group of people only using hand tools.

There _is_ a danger that society forgets how to do these things. During that house-building exercise, there were many tricks of the trade that, while likely documented somewhere in a book, would have been difficult to reproduce without seeing a demonstration. From the standpoint of “does it matter?” it depends on what you care about. We absolutely do not need cruck-framed houses with scribed joints. Modern construction is faster and cheaper and lasts long enough. But it would sadden me greatly if practices like this faded from memory, because it’s one of those things that makes you gasp “wow!” when you see it. And your appreciation only deepens when you try it yourself.
