It's totally true. I was doing Advent of Code before I had any training or work in programming at all, and a lot of it can be done with just thinking through the problem logically and using basic problem solving. If you can reason a word problem into what it's asking, then break it down into steps, you're 90% of the way there.
Comparing previous years, they're exactly what I'd expect, to be honest. Only people serious about completion will...well...complete it. Even if they do not know any code, if you pick something well-documented like Python or whatever, it should not be a tremendous challenge so long as you have the drive to finish the event. Code isn't exactly magic, though it does require some problem-solving and dedication. Since this is a self-paced event that does not offer any sort of immediate reward for completion, most people will drop out due to limited bandwidth needing to be devoted to everything else in their lives. That versus, say, a college course where you paid to be there and the grade counts toward your degree; there's simply more at stake when it comes to completing the course.
But, speaking to the original question as to the number of newbies that go all the way, I'd say one cannot expect to increase their skills in anything if one sticks in their comfort zone. It should be hard, and as a newbie who participated in previous years, I can confirm it often is. But I learned new things every time I did it, even if I did not finish.
I have to say, I've read many out-of-touch comments on HN over the years but this is definitely among the most out there, borderline delusional comments I've ever seen!
The idea that anyone who doesn't know any code would:
1) Complete in Advent of Code at all.
2) Complete a single part of a single problem.
let alone, complete the whole thing without it being a "tremendous challenge"...
is so completely laughable it makes me question whether you live on the same planet as the rest of us here.
Getting a person who has never coded to write a basic sort algorithm (i.e. bubble sort) is already basically impossible. I work with highly talented non coder co-workers who all attended tier-1 universities (e.g. Oxford, Harvard, Stanford) but for finance/business related degrees, I cannot get them to write while/foreach loops in Python, and simply using Claude Code is way too much for them.
If you are even fully completing one Advent of Code problem, you are in the top 0.1% of coders, completing all of them puts you in the top 0.001%.
I can't begin to describe how valuable your input has been through this whole thread about something you're quite possessive and passionate about, which surely places you in a position to aggressively dismiss any other possible way of looking at it! Wow, love learning about new perspectives on HN!
Wishing you best of luck in AoC, Life and Love but I imagine someone like you doesn't need it, being a complete toolbox and all.
P.S.: Tell your coworkers I'm sorry they have to put up with you.
You're the person saying Advent of Code is "so easy" that anyone even people with no coding ability at all should find it do-able, which is totally diminishing the difficulty of the problems, and asserting your own genius, i.e. that you found it totally trivial.
I am the person saying that actually, stuff like Advent of Code is incredibly difficult and 99% of active programmers aren't able to complete it, let alone people who don't code.
I am not an elitist at all, unlike yourself, I don't find completing "Advent of Code" easy, in fact, it would take me a long time to complete it, more time than I have available in my busy life in the average December. And I doubt I would be able to complete it 100% without looking up help, getting hints, or using LLMs to help.
You clearly didn't read my whole original comment before mouthing off. Go back and do that, you'll find that I pointed out most do not complete it, that it is supposed to be challenging and I never called it "easy" as you imply ("not tremendously difficult" =/= "easy")
Heck, I even talked about having to be serious about completion, and you could not bother to read the whole comment, then proceed to call me delusional? FFS, I am now praying for your co-workers and I'm not even religious.
Did YOU even read your original comment? You asserted that people who have never coded could complete the event!
Did you realize only roughly 500 people of the > 1M who are registered for advent of code even complete it?
You said "it should not be a tremendous challenge", i.e. not that big of a deal even if you don't know how to code. Which is absolutely diminishing the difficulty of the event, I mean, come on man...
This is why I'm asserting you are quietly oblivious to the abilities of most people. I am asserting that most people who CAN code, cannot complete the event, yet alone non-coders. I am a very active coder (for fun mostly these days, but also sometimes for work), but I could not complete Advent of Code. Maybe if I took all of December off work to dedicate serious time, but even then I wonder if it's possible without looking at hints/LLM-help etc.
I often try and help my co-workers who are working on AI based side-projects for fun, so I have a strong insight into the abilities of non-coding smart people, and the reality is that yes, they get very turned off as soon as you get anything more complex than for-loops and if-statements. This isn't me being mean to co-workers, this is the reality of things I have experienced. It's not a brains thing, they can understand more complex stuff, but they don't want to, they find it annoying, boring, not worth the time/effort etc. So the idea of them learning dynamic programming, DFS/BFS, more complex data structures etc, is well, just not going to happen.
My point is that you are effectively saying, "oh just about anyone can do Advent of Code if they want to", is totally not grounded in any sort of reality.
The amount of injected implication you are imposing on everything I said...this is some seriously unhinged gaslighting in effort to obfuscate the fact that you came out of the gate calling someone delusional over a comment you barely understood. We're wasting each other's time, so I'm out.
