blog.replay.ioReplay Time Travelogue: Improving Nadia’s “Debugging with AI” Results Using Replay MCP

5 May

A few months ago, I wrote an article on whether AI can replace an experienced developer. The verdict: of course not! Well, @acemarke.dev took it as his personal mission to prove me wrong 😅 And he did! His army of robots solved all the bugs from the original article blog.replay.io/replay-time-...

developerway.comDebugging with AI: Can It Replace an Experienced Developer?Can AI actually debug complex React/Next.js issues? I tested it on three real bugs, investigated the root cause myself and wrote down the results.

Although I'm even more convinced now in my original statement: only a very experienced developer like Mark can actually guide that robo-invasion to victory without them falling off a cliff 😜. Original investigation: www.developerway.com/posts/debugg...

For books/blogs it's even worse 😅 Ask me how I know...

Josh W. Comeau@joshwcomeau.com

I’ve spoken to a few course creators now, and we’re all seeing the same trend. Revenue down 50%+. Fewer people engaging with our content. People switching to LLMs, which slurp up all of our work and regurgitate it, without consent or compensation. It feels pretty bleak. 😅

Question: should I continue with performance improvements for my blog, or is it good enough? 🤔 Can't really tell.

Kicked off the "Testimonials" section for the "Web Performance Fundamentals" book (www.getwebperf.com) with very lovely feedback from the early readers. "Detailed", "on topic", and "simple" are the general themes of the feedback so far :)

25 Aug 2025

I tried really hard to deliver pretty advanced content in such a way that it's simple and easy to understand, while trying to avoid talking down to the readers as if they were children. Looks like it worked 😊 To quote a reviewer: "Like a talk with a colleague in simple words and on topic".

This is happening and pretty soon! The new book is coming, final polish in progress. In the meantime, which title do you like best? "Beyond Re-renders Web Performance Fundamentals for React Developers" "Web Performance Fundamentals Profile & Optimize React Web Apps" 🧵👇🏼

View full thread

Core target audience: middle to senior React developers who want to deepen their knowledge and tap into web performance. Secondary target audience: any frontend developer interested in web performance who doesn't mind dealing with React on occasion.

It's absolutely not for beginners, though; prior experience is pretty much mandatory.

The rationale👇🏼 The book is all about _web performance_: how to investigate, measure, and understand it. 70% of the book has nothing to do with React itself: it's about fundamental web knowledge applicable to any web app, SPA or not. So I'd like to avoid "React" in the title.

Nevertheless, all examples are written in React, some of the aspects are deeply intertwined with React's specifics (like SSR), and some of them are purely React specifics, like React Server Components. So, keeping "React" somewhere in the subtitle seems fair.
