Well I mean the biggest thing that would be the ultimate ideal would be anything that can maximize the ability to bring existing unity projects over to godot. IE minimal refactoring needed.
Big thing is not just getting people to start their new projects, but what about those who have spent 3+ years mastering their game, only to have the rug pulled out from under them when it was 80% of the way to release worthy.
I do agree on the whole, It's the next phase of automation. The real problem stems from the fact that we hold onto the system where a tiny handful of people get the full benefit of the productivity, while the others are paid in time incriments which value goes down with demand, so as more jobs are automated or assisted (to allow more work with less people), supply demand devalues the labor.
