Ah, another thread filled with people sharing anecdotes about how they asked Claude to one-shot an entire project that would take people weeks if not months.

#782It is very funny to start your article off with a bunch of breathless headlines about agents replacing human coders by the end of 2025, none of which happened, then the rest of the article is "okay but this time for real, an agent really WILL replace human coders."
Re: Opus 4.5 is not the normal AI agent experience that I have had thus far
#783A lot of the complaints about these tools seems to revolve around their current lack of ability to innovate for greenfield or overly complex tasks. I would agree with this assessment in their current state, but this sentiment of "I will only use AI coding tools when they can do 100% of my job" seems short-sighted. The fact of the matter, in my experience, is that most of the day to day software tasks done by an indiv…
The vast majority of engineers aren't refusing to use AI until it can do 100% of their job. They are just sick of being told it already can, when their direct experience contradicts that claim.

#784I'm tired of constantly debating the same thing again and again. Where are the products? Where is some great performing software all LLM/agent crafted? All I see is software bloatness and decline. Where is Discord that uses just a bunch of hundreds megs of ram? Where is unbloated faster Slack? Where is the Excel killer? Fast mobile apps? Browsers and the web platform improved? Why Cursor team don't use Cursor to get…
This deserves more upvotes. Even if there is a "fully vibe-coded" product that has real customers, the fact that it's vibe-coded means that others can do the same. Unless you have a secret LLM or some magical prompts that make the code better/more efficient than your competitions, your vibe coded product has no advantage over competition and no moat. What actually matters is everything else -- user experience (which…

But that's precisely why you don't hear about these products: the creators don't disclose that they were vibe-coded, because if they do, that invites competition.
I personally know of four vibe-coded products that generate over $10k/mo. Two of them were made by one friend, one was made by another, and the last one by my cousin. None of these people are developers. But they are making real money.

We all have a cousin that makes $10k/mo and has super powers

#786It’s a bit strange how anecdotes have become acceptable fuel for 1000 comment technical debates. I’ve always liked the quote that sufficiently advanced tech looks like magic, but its mistake to assume that things that look like magic also share other properties of magic. They don’t. Software engineering spans over several distinct skills: forming logical plans, encoding them in machine executable form(coding), making…
Well said.

It's a very subjective topic. Some people claim it increases their productivity 100x. Some think it is not fit for purpose. Some think it is dangerous. Some think it's unethical.
Weirdly those could all be true at the same time, and where you land on this is purely a matter of importance to the user.
> Yet, I’d love to see less discussion driven by anecdotes and more discussion about productizing these tools, where they work, usage methodologies, missing tooling, KPIs for specific usecases. And don’t get me started on current evaluation frameworks, they become increasingly irrelevant once models are good enough at instruction following.
I agree. I've said earlier that I just want these AI companies to release an 8-hour video of one person using these tools to build something extremely challenging. Start to finish. How do they use it, how does the tool really work. What's the best approaches. I am not interested in 5-minute demo videos producing react fluff or any other boiler plate machine.
I think the open secret is that these 'models' are not much faster than a truly competent engineer. And what's dangerous is that it is empowering people to 'write' software they don't understand. We're starting to see the AI companies reflect this in their marketing, saying tech debt is a good thing if you move fast enough....
This must be why my 8-core corporate PC can barely run teams and a web browser in 2026.
Re: Opus 4.5 is not the normal AI agent experience that I have had thus far
#788What bothers me about posts like this is: mid-level engineers are not tasked with atomic, greenfield projects. If all an engineer did all day was build apps from scratch, with no expectation that others may come along and extend, build on top of, or depend on, then sure, Opus 4.5 could replace them. The hard thing about engineering is not "building a thing that works", its building it the right way, in an easily unde…
Even if you are going green field, you need to build it the way it is likely to be used based a having a deep familiarity with what that customer's problems are and how their current workflow is done. As much as we imagine everything is on the internet, a bunch of this stuff is not documented anywhere. An LLM could ask the customer requirement questions but that familiarity is often needed to know the right questions to ask. It is hard to bootstrap.
Even if it could build the perfect greenfield app, as it updates the app it is needs to consider backwards compatibility and breaking changes. LLMs seem very far as growing apps. I think this is because LLMs are trained on the final outcome of the engineering process, but not on the incremental sub-commit work of first getting a faked out outline of the code running and then slowly building up that code until you have something that works.
This isn't to say that LLMs or other AI approaches couldn't replace software engineering some day, but they clear aren't good enough yet and the training sets they have currently have access to are unlikely to provide the needed examples.

Except for maybe an "Excel killer", all those things you listed are not things people are willing to pay for. Also agents are bad at that kind of work (most devs are bad at that stuff, it's why it was something people whined about even before agents). And funnily enough there are products and tools that are essentially less bloated slack/discord. Have you heard of https://stoat.chat/ (aka revolt) or https://pumble.co…
Not willing to pay for? How can you be sure? For example explain then why many gamers are ditching Windows for Linux and buying hardware from Valve... There must be a reason. Every person I talked to that uses Excel hate how slow it is, same for teams and many other products. Finally, were the mentioned products built with vibe coding?
Generally if something is fast enough/efficient enough that a paying customer can use it without having to worry or actively think about performance and un-bloatedness, that's enough for them. The only people who might complain still are developers who are bothered by the inefficiency and are technically literate enough to notice it, and maybe the users with less powerful/capable devices than the ones the big paying customers use. Generally these groups of people are not the actual customers of these products.
The people who actually pay for slack and discord (eg enterprises that need workplace chat app and decided to go with the "gold standard", consumers with discord servers and such) need the features/tradeoffs choosing featuers over efficiency causing that bloat. They just don't all need the exact same set of those features as the other customers. So because customers are willing to pay for all these features the product tries to ship all of them and becomes bloated.
> Every person I talked to that uses Excel hate how slow it is
But do they make the purchasing decisions behind using Excel?
To be clear I am not really arguing that bloat/overly enterprisey products are good. What I mean that you don't see the world exploding with more elegant products now with agents for the same reason you didn't see the world exploding with them before agents either: the people who pay for those products and build them for a living are not incentivized or necessarily even rewarded for choosing to make them more efficient or elegant when there are other things that customers are asking for with more $$$ behind them.

>So my verdict is that it's great for code analysis, and it's fantastic for injecting some book knowledge on complex topics into your programming, but it can't tackle those complex problems by itself. I don't think you've seen the full potential. I'm currently #1 on 5 different very complex computer engineering problems, and I can't even write a "hello world" in rust or cpp. You no longer need to know how to write co…
How are you qualified to judge its performance on real code if you don't know how to write a hello world? Yes, LLMs are very good at writing code, they are so good at writing code that they often generate reams of unmaintainable spaghetti. When you submit to an informatics contest you don't have paying customers who depend on your code working every day. You can just throw away yesterday's code and start afresh. Clau…
I know what's like running a business, and building complex systems. That's not the point.
I used highload as an example because it seems like an objective rebuttal to the claim that "but it can't tackle those complex problems by itself."
And regarding this:
"Claude is very useful but it's not yet anywhere near as good as a human software developer. Like an excitable puppy it needs to be kept on a short leash"
Again, a combination of LLM/agents with some guidance (from someone with no prior experience in this type of high performing architecture) was able to beat all human software developers that have taken these challenges.
