I always read it as making the same mistakes as you initially did and either failing to learn from them or not even trying to improve. Maybe you haven’t even explored enough approaches to see what actually works and what doesn’t and most importantly, in which circumstances.

For example, someone might do CI/CD with manually created pipelines in Jenkins (the web UI variety) with stuff like JDK configured directly on the runner nodes. They might never have written a Jenkinsfile, or tried out Docker for builds and therefore are slow and have to deal with brittle plugins and environment configuration. They might also be unaware of how GitHub Actions could benefit them, or the more focused approach of GitLab CI or even how nice Woodpecker CI can be, especially for simpler setups.
