I’ve been coding for the past 10 years and I like to think I’m at a point where I know my way around code.
I’ve been working on my startup as a solo developer for the past year. The project has grown to about 30k LOC—it’s not big, but not small either.
Six days ago, I talked with my associate (he’s the one financing the project) about buying the Cursor Ultra plan, and he agreed.
Today, exactly six days since I last touched a single line of code, the project has grown as much in these six days as it used to in two weeks.
I thought I understood what Andrej Karpathy meant when he said “The hottest new programming language is English” (obviously, I’ve used Grok, ChatGPT, and countless other tools to develop the project up until this point, but I still had to code—a lot). But now I realize what he actually meant.
From feeding it (Cursor) tens of files at once to find bugs (mind you, not only syntax, but also business logic), to handling API documentation with hundreds of files (funny how Cursor can’t read PDFs, but it created its own Python script to transform the PDF into a .txt file, which it then organized into a reference file it can read anytime I ask about said API), to implementing features… this thing is jaw-droppingly good. I feel like I have superpowers. It’s insane. I literally can’t find more words to describe how this tool has changed my life when it comes to work—and again, it’s only been six days!
Thank you, Cursor team. I hope you realize you’ve created the iPhone moment for the IT industry.
Like bro I been screaming this thing… i’m 4 months into using cursor and it’s just crazy I’ve been rambling about this thing it’s all I ramble about on Twitter that’s where I’m most active on… am like why would they let this into the world for this cheap do you get me? Bro I was mindblow I could tell it to refactor an e entire codebase into a different framework or language.
I feel like I just typed in a GTA cheat code for infinite ability cause it is
I agree. What’s surprising to me though is that you have 10 years of coding experience; I’m just a nocode guy who knows how to build but doesn’t know the syntax or how to write it manually. Yet I’ve built 4 applications in the last 2 months with cursor!
Hi there, nice what you are saying, I would like that you have something into account, 30k LOC is small yet and it is not bad, what I mean is that you are in a point where things could be more complicated when your project grows up. I tell you this because I have more than 150k, but when I had 80 things started to get complicated. I modified my architecture, now I use a hexagonal one. I noticed that there was some code that was repeated, mappers that complicated things in my frontend, and interfaces and types that didn’t match the backend. Also, logic that was of the domain layer duplicated all over the place.
Having said that, I also love Cursor;however,take as many measures as possible to ensure your code is built in the best way.
Same situation for me — I constantly had to outsource work on my project to Coding House, which was not only expensive but also meant waiting for everything, including every fix or change, and paying again each time.
Now Sonnet 4.5 is building my application from scratch. I’ve got my own VPS, full Ubuntu server configuration, postfix, SSL — it’s simple stuff, but why struggle when the agent did it all for me and even added extra tweaks and security hardening!
The code is a dream now. At the beginning there were lots of errors, but that was my fault since I didn’t know what I wanted or which technology to use. Now that I’ve figured it out, the only limits are my time and imagination… oh, and tokens xD.
Yea, that is what happens with current models over time. Lots of duplication, bad choices even unfinished features nobody remembers anymore. And no matter how much you make rules and instructions, this is unavoidable. Sometimes you ask clean-up, and it won’t work either as good as you could hope for.
But hey, last year same time we didn’t have even this much, so maybe next year this time that 150k is easy peasy for the AI.
I had a team of 12 devs based out in the Philippines… up until a few months ago.
Now I have 1 cursor subscription and no devs - just me and cursor doing the work of 12 devs.
RIP junior devs and virtual assistants.
Also RIP designers - my clients just play with claude and send over mockups. Several of my clients were paying design teams 5k a month to a design team - now they have a $20 a month claude subscription, no meetings and instant design changes. It’s not perfect but it is infinitely better than endless meetings, days between design rounds etc.
I really feel for those economies though - a huge percentage of developing economies have been devoted to capturing the outsourcing/offshoring wave. But with AI it’s all coming back onshore and inhouse.
I regularly get my old devs reaching out asking for work and I’m straight up in telling them that AI now does everything they can do - one day it’ll probably replace me too. Thankfully coding is still complicated enough that you need a human in the loop - for now.
