It's such a visual and experiential thing that writing true success criteria it can iterate on seems like borderline impossible ahead of time.
Or slower, when the LLM doesn't understand what I want, which is a bigger issue when you spawn experiments from scratch (and have given limited context around what you are about to do).
Which is curious since prototyping helps a lot in gamedev.
> "IDEs/agent swarms/fallability. Both the "no need for IDE anymore" hype and the "agent swarm" hype is imo too much for right now. The models definitely still make mistakes and if you have any code you actually care about I would watch them like a hawk, in a nice large IDE on the side. The mistakes have changed a lot - they are not simple syntax errors anymore, they are subtle conceptual errors that a slightly sloppy, hasty junior dev might do. The most common category is that the models make wrong assumptions on your behalf and just run along with them without checking. They also don't manage their confusion, they don't seek clarifications, they don't surface inconsistencies, they don't present tradeoffs, they don't push back when they should, and they are still a little too sycophantic. Things get better in plan mode, but there is some need for a lightweight inline plan mode. They also really like to overcomplicate code and APIs, they bloat abstractions, they don't clean up dead code after themselves, etc. They will implement an inefficient, bloated, brittle construction over 1000 lines of code and it's up to you to be like "umm couldn't you just do this instead?" and they will be like "of course!" and immediately cut it down to 100 lines. They still sometimes change/remove comments and code they don't like or don't sufficiently understand as side effects, even if it is orthogonal to the task at hand. All of this happens despite a few simple attempts to fix it via instructions in CLAUDE . md. Despite all these issues, it is still a net huge improvement and it's very difficult to imagine going back to manual coding. TLDR everyone has their developing flow, my current is a small few CC sessions on the left in ghostty windows/tabs and an IDE on the right for viewing the code + manual edits."
Anyone wondering what exactly is he actually building? What? Where?
> The mistakes have changed a lot - they are not simple syntax errors anymore, they are subtle conceptual errors that a slightly sloppy, hasty junior dev might do.
I would LOVE to have jsut syntax errors produced by LLMs, "subtle conceptual errors that a slightly sloppy, hasty junior dev might do." are neither subtle nor slightly sloppy, they actually are serious and harmful, and no junior devs have no experience to fix those.
> They will implement an inefficient, bloated, brittle construction over 1000 lines of code and it's up to you to be like "umm couldn't you just do this instead?"
Why just not hand write 100 loc with the help of an LLM for tests, documentation and some autocomplete instead of making it write 1000 loc and then clean it up? Also very difficult to do, 1000 lines is a lot.
> Tenacity. It's so interesting to watch an agent relentlessly work at something. They never get tired, they never get demoralized, they just keep going and trying things where a person would have given up long ago to fight another day.
It's a computer program running in the cloud, what exactly did he expected?
> Speedups. It's not clear how to measure the "speedup" of LLM assistance.
See above
> 2) I can approach code that I couldn't work on before because of knowledge/skill issue. So certainly it's speedup, but it's possibly a lot more an expansion.
mmm not sure, if you don't have domain knowledge you could have an initial stubb at the problem, what when you need to iterate over it? You don't if you don't have domain knowledge on your own
> Fun. I didn't anticipate that with agents programming feels more fun because a lot of the fill in the blanks drudgery is removed and what remains is the creative part.
No it's not fun, eg LLMs produce uninteresting uis, mostly bloated with react/html
> Atrophy. I've already noticed that I am slowly starting to atrophy my ability to write code manually.
My bet is that sooner or later he will get back to coding by hand for periods of time to avoid that, like many others, the damage overreliance on these tools bring is serious.
> Largely due to all the little mostly syntactic details involved in programming, you can review code just fine even if you struggle to write it.
No programming it's not "syntactic details" the practice of programming it's everything but "syntactic details", one should learn how to program not the language X or Y
> What happens to the "10X engineer" - the ratio of productivity between the mean and the max engineer? It's quite possible that this grows a lot.
Yet no measurable econimic effects so far
> Armed with LLMs, do generalists increasingly outperform specialists? LLMs are a lot better at fill in the blanks (the micro) than grand strategy (the macro).
Did people with a smartphone outperformed photographers?
All of the real world code I have had to review created by AI is buggy slop (often with subtle, but weird bugs that don't show up for a while). But on HN I'm told "this is because your co-workers don't know how to AI right!!!!" Then when someone who supposedly must be an expert in getting things done with AI posts, it's always big claims with hand-wavy explanations/evidence.
Then the comments section is littered with no effort comments like this.
Yet oddly whenever anyone asks "show me the thing you built?" Either it looks like every other half-working vibe coded CRUD app... or it doesn't exist/can't be shown.
If you tell me you have discovered a miracle tool, just some me the results. Not taking increasingly ridiculous claims at face value is not "fear". What I don't understand is where comments like yours come from? What makes you need this to be more than it is?
I've worked extensively in the AI space, and believe that it is extremely useful, but these weird claims (even from people I respect a lot) that "something big and mysterious is happening, I just can't show you yet!" set of my alarms.
When sensible questions are met with ad hominems by supporters it further sets of alarm bells.
They have to maintain the hype until a somewhat credible exit appears and therefore lash out with boomer memes, FOMO, and the usual insane talking points like "there are builders and coders".
>Anyone wondering what exactly is he actually building? What? Where?
this is trivially answerable. it seems like they did not do even the slightest bit of research before asking question after question to seem smart and detailed.
Quite insightful.
I've been increasingly using LLM's to code for nearly two years now - and I can definitely notice my brain atrophy. It bothers me. Actually over the last few weeks I've been looking at a major update to a product in production & considered doing the edits manually - at least typing the code from the LLM & also being much more granular with my instructions (i.e. focus on one function at a time). I feel in some ways like my brain is turning into slop & I've been coding for at least 35 years... I feel validated by Karpathy.
1. Manual coding may be less relevant (albeit ability to read code, interpret it and understand it will be more) in the future. Likely already is.
2. Any skill you don't practice becomes "weaker". Gonna give you an example. I play chess since my childhood, but sometimes I go months without playing it, even years. When I get back I start losing elo fast. If I was in the top 10% of chess.com, I drop to top 30% in the weeks after. But after few months I'm back at top 10%. Takeaway: your relative ability is more or less the same compared to other practitioners, you're simply rusty.
even dealing with api's that have MCP servers the so called agents make a mess of everything.
my stuff is just regular data stuff - ingest data from x - transform it | make it real time - then pipe it to y
9/10 of the most important social media users use X, like or loath it
Nevermind the fact he became successful _because_ of his skills and his brain.
