Following is some of the cases where competing software won this or that battle, and I am jealous since I want everyone to use what I like:

  • Kurbenetes is written in Go, and not Rust. It appears to be the most popular container orchestration system, and is among the hottest of new software projects, while having lots of momentum.
  • Grafana is also written in Go, and not Rust. It produces the most pretty graphs I've seen yet, and is very featureful, while also boasting hundreds of contributers.
  • Markdown is a far more popular light-weight markup language than the far more advanced reStructuredText. It's particularly sad when it's not used where it's needed most... documenting large projects (example).
