Every piece of software has an expiration date. You can extend its lifespan, but technology keeps moving. What was considered standard on the backend five years ago may look completely different today. I think that's a good thing. Rails worked extremely well for its time, especially around 2007–2015, but it started to show its age as newer, more capable languages and runtimes matured.

We should be celebrating the fact that we can now port almost anything with far less effort, or modernize an existing stack to meet today's performance expectations, requirements, and engineering standards.
