I'm a quite senior frontend using React and even I see Sonnet 4.5 struggle with basic things. Today it wrote my Zod validation incorrectly, mixing up versions, then just decided it wasn't working and attempted to replace the entire thing with a different library.

There’s little reason to use sonnet anymore. Haiku for summaries, opus for anything else. Sonnet isn’t a good model by today’s standards.

I have been chastened in the opposite direction by others. I've also subjectively really disliked Opus's speed and I've seen Opus do really silly things too. But I'll try out using it as a daily driver and see if I like it more.

What 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…

Not necessarily responding to you directly, but I find this take to be interesting, and I see it every time an article like this makes the rounds. Starting back in 2022/2023: - (~2022) It can auto-complete one line, but it can't write a full function. - (~2023) Ok, it can write a full function, but it can't write a full feature. - (~2024) Ok, it can write a full feature, but it can't write a simple application. - (~2…

Starting back in 2022/2023:

- (~2022) "It's so over for developers". 2022 ends with more professional developers than 2021.

- (~2023) "Ok, now it's really over for developers". 2023 ends with more professional developers than 2022.

- (~2024) "Ok, now it's really, really over for developers". 2024 ends with more professional developers than 2023.

- (~2025) "Ok, now it's really, really, absolutely over for developers". 2025 ends with more professional developers than 2024.

- (~2025+) etc.

> Why does a human need to read this code at all? I use a custom agent in VS Code that tells Opus to write code for LLMs, not humans. Think about it—why optimize for human readability when the AI is doing all the work and will explain things to you when you ask?

Most software engineers are seriously sleeping on how good LLM agents are right now, especially something like Claude Code. Once you’ve got Claude Code set up, you can point it at your codebase, have it learn your conventions, pull in best practices, and refine everything until it’s basically operating like a super-powered teammate. The real unlock is building a solid set of reusable “skills” plus a few agents for th…

I use claude code all the time, but never allow it to edit my code. It proposes spaghetti code almost 80% of time

Opus 4.5 is writing code that Opus 5.0 will refactor and extend. And Opus 5.5 will take that code and rewrite it in C from the ground up. And Opus 6.0 will take that code and make it assembly. And Opus 7.0 will design its own CPU. And Opus 8.0 will make a factory for its own CPUs. And Opus 9.0 will populate mars. And Opus 10.0 will be able to achieve AGI. And Opus 11.0 will find God. And Opus 12.0 will make us a time…

Just one more OPUS bro.

>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…

None of the problems you've shown there are anything close to "very complex computer engineering problems", they're more like "toy problems with widely-known solutions given to students to help them practice for when they encounter actually complex problems".

I think you misunderstood, it's not about solving the problem, is about finding the most efficient solution. Give it a shot, and see if you can get to the top 10 on any task.

The point is these problems are well understood and solved, solving them well with AI doesn’t mean anything as you’re just reciting something that’s already been done already.

Insanely difficult to you maybe because you stopped learning. What you cannot create you don't understand.

Are you honestly saying that building a new spec-compliant WebAssembly runtime from scratch isn't an absurdly difficult project?

i took the time to review your python wasm project and restate the fact that you seem to have 0 idea about how a compiler works.

Its simple and rigid rules an AI can pick up easily. If you lack this knowledge people that have it will simply stop the conversation when you resort to shouting louder and more often.

This does not make your point more valid. If you notice people not engaging with you - that's the reason. You simply don't learn, you just look around who shares your opinion with no backed results.

Why not show benchmarks or sth ;)

> I don’t know if I feel exhilarated by what I can now build in a matter of hours, or depressed because the thing I’ve spent my life learning to do is now trivial for a computer. Both are true.

I'm not so sure... I mean it's true that regardless of if you are a beginner, junior, or 'senior', if you say "build me an instagram clone" Opus 4.5 will probably do a decent job. I think the skills go still in understanding architecture, and just knowing where pitfalls and problems can arise, or even making some important 'abstraction cut' prompts. I think applications can still grow to a point where you still need to prompt at specific domains only, or the model will fail to do everything you want it to - especially if you give it massive 'fix this this this anad that too' prompts
