I work on a giant in-house lab application written in grails. It has 100s of lab workflows. The main concern is the old techstack. Everyone wants to discontinue the application and move to a modern stack like python and react.

The main reason for choosing grails was GORM for 800 tables db. I've been working on it for the past 3 years and i have fallen in love with grails. It's orm , it's dynamic getters, it's simple syntax.

If they discontinue the app, it will break my heart and i might even lose my job

I personally feel with the rise of ai, language is not even the issue anymore. And the cost of replacing the entire application will be astronomical.

What's your opinion on this?
