“As soon as you get to the point where like every developer is 10 times as productive, merging their code becomes this incredibly complicated problem because I, you and I work at the same time for two or three hours. We make, you know, 30,000 line change each. Mine makes it in first, ah, and it gets merged and then you come along and I have literally changed our logging system and our, like, you know, our architecture here and APIs. That you were using. And so it's not going to be a simple, it's not a simple, let's fix the merge conflicts. It's like, you're going to have to re-envision and re-imagine and re-implement your change on my change.”

Yegge: Senior engineers with 12-15 years experience hate vibe coding most
“It's not junior engineers. It's not non-engineers. They're all vibe coding. It's senior engineers, senior leaders people who have, so basically you can narrow it down to. 12 to 15 years of experience. They hate vibe coding and they hate AI and they're online g…”
Yegge: Claude Code is too hard for most engineers
“And the answer is it's too hard. It's too hard. You have to be able to read, man, most engineers, honestly, like to them, five paragraphs is an essay. Okay. And with cloud code, you've got to read waterfalls of not just information, but also code and diffs, ri…”
