It’s because depending on the person the newest model crossed the line into being useful for them personally. It’s not like a new version crosses the line for everyone. It happens gradually. Each version more and more people come into the fold.
You get new people recommending the latest version all the time to people who are unconvinced because that version is usually what brought them into the fold.
What you’re mocking is somewhat of a signal of actual improvement of the models and that improvement as a result becoming useful to more and more people.
