Been writing software for like 20 years now and I love it. I am also a fan of AI-assisted coding, but I only just started using Cursor. Gosh I do not like it at all for a simple reason: since I didn't write the code, in order to understand it I have to read it. But gaining understanding that way takes longer than writing it myself does.
When you write the code, you understand it. When you read the code produced by an agent, you may eventually feel like you understand it, but it's not at the same deep level as if your own brain created it.
I'll keep using new tools, I'll keep writing my own code too. Just venting my frustrations with agentic coding because it's only going to get worse.
Yep. I had a few vibe coded projects that were fairly far along and then things broke. The code was so convoluted and it took me so long to understand that I just opted to rewrite everything from scratch without AI. Sure, it took longer but I understood all of it.
No joke: Maybe that is the current value of vibe coding. It helps you get started with a crappy version. In your experience, which one do think would take longer? (1) Vibe code until it breaks, then you rewrite everything from scratch or (2) Write everything from scratch. I don't vide code (yet?), but I do use LLMs to get ideas about how to solve problems and look at same code, especially when I don't what library function to call.
Yeah I do use it for prototyping when I just want to get some version working, so I'm not knocking that, but it's more so trying to warn pure vibe coders that they won't get far if they don't eventually buckle down and write code themselves, for the LLMs will break the code at some point.

I remember reading Joel Spolsky's blog 25 years ago, and he wrote something like: "It is harder to read code than to write code." I was quite young at that stage in my programming journey, but I remember being simultaneously surprised and relieved -- to know that reading code was so damn hard! I kept thinking if I just worked harder at reading code that eventually it would be as easy as writing code.
“Indeed, the ratio of time spent reading versus writing is well over 10 to 1. We are constantly reading old code as part of the effort to write new code. ...[Therefore,] making it easy to read makes it easier to write.”
― Robert C. Martin, Clean Code: A Handbook of Agile Software Craftsmanship
Also:
Everyone knows that debugging is twice as hard as writing a program in the first place. So if you're as clever as you can be when you write it, how will you ever debug it?

In summary: write simple code, it's easy to read and understand - by future you who forgot why you did something and others.
When you write the code, you understand it. When you read the code produced by an agent, you may eventually feel like you understand it, but it's not at the same deep level as if your own brain created it.
