It’s not about frustration, unwillingness to learn, or dismissing the tool altogether. My point is about trust. I just can’t imagine a Next.js app being as easily maintainable 10 years down the road as a Rails one. Honestly, I can’t even picture upgrading to a new major version without breaking something, because the pace of changes is just too fast. Sure, it’s great for small, simple projects. But building a business on it and risking breakages or dropped support? Not for me.
This isn't accurate. Most Next shops continue to use Page Router with no problems. We have an internal tool that uses both Page Router with React 13 and App Router with React 19, all seamlessly supported OOB, including frontend composition. So, again, I have to assume most of the FUD is rooted in inexperience.
