While knowledge is always great, I would encourage people not to seek advice from successful people like this (survivorship bias).

Moreover I am not sure it is even good advice? Would you advise a 17 y.o. to learn how transistors work or how to code (i.e. is LLM training the right level in the stack)? LLM training, a discipline where relevant work is already out of reach for 99.999% of budgets really as essential as this post implies?

I am kind of amazed how negative the comments are here, especially on HN. Learning to hack something together in high school using the latest technology (vacuum tubes, radios, microprocessors, web/javascript) has been a common theme in the tech world for generations. With LLMs and online tutorials, this isn't even a difficult suggestion. Do people think learning new tech is somehow wasted effort?

> I am kind of amazed how negative the comments are here, especially on HN.

I can't recall or point out exactly when, but there is a stark before/after moment where the opinions of anything pg went from "Interesting and maybe true in some ways" to what we see today, lots of knee-jerk reactions and hardly any comments about the actual content.

Hazarding a guess, I think the moment Altman became the CEO and later during COVID, the sentiment seemed to have been shifting towards what we see today. But this is all based on hazy memory, rather than looking at the data. I'm sure there is a blog post waiting to be written about analyzing the sentiment of comments to PGs articles on HN, and you'll see a shift somewhere.

If he has said "to learn the math and programming skills needed to understand how to build LLMs" it'd have been much more positively received.

I do not think it is a proper thing to do for 17 y.o., unless they are exceptionally mathematically gifted, as proper understanding of how LLMs are trained requires a good grasp of calculus, understanding modern OS and SDE tools for proper implementation of pipeline etc. I'd rather simply write another mnist implementation and check if I really like all that AI stuff at first place. Even then, before going into matur…

Why would you tell people that the correct order is to build foundational knowledge before exploring a subject? For some (many?) people, a 'proper' understanding develops _after_ the exploration.

Personally I don't see the problem, as long as you're aware there is survivorship bias involved here.

What's the alternative really, seek advice from unsuccessful people? That seems worse :)

Personally I do both, read about what worked for people, also read about what didn't work for people, then ignore both and do whatever the fuck I want.

I think he is basically saying YC has enough startups that are just making API calls.

> I do not think it is a proper thing to do for 17 y.o If I'd get a buck every time someone said something like this to me when I was in the 13-18 range, I wouldn't have a ton of money, but it's so very annoying when people tell you this. Regardless if they're "gifted" or not, regardless if you believe in myths like that or not, let children explore what they want to explore, even if you don't understand what it is o…

Agree with this - started programming through learning scripting in ROBLOX when I was like 12 (this was back like 17 or 18 years ago) and it developed into a life-long passion for software engineering. I am thankful I had people around me (my parents), who were aware enough to realize I wasn't just playing video games and gave me the time I needed on the computer to learn and experiment with programming...

This also meant that by the time I was actually offered to take a programming class in school (junior year of HS), I had already been able to self-teach myself well beyond what that class was covering, thanks to just working on random projects that scratched an itch I had at the time, looking up anything I didn't know or understand, and internalizing those concepts over time.

In short though, I definitely agree, young kids and teens (and also, frankly, adults too!) should be encouraged to explore things that they have a passion for, without being told 'you need to go to school for this' or 'you cant understand this at your age'

Now I'm curious, do people actually tried to hack vacuum tubes or other big servers that's barely 1MB RAM? It seems like another thing that needs big investment to work properly, unlike those other techs where results can be shown even with little materials.

Intuitively, I would guess that they have a better grasp of what made them fail than successful people have of what made them succeed.
