Wish I could help but after a hiatus of nearly 3 decades I’m only just starting tentatively to get back into coding by exploring a few modern languages before diving in to learn one or two of them fully.
It would be a shame for Ubuntu Unity to go under. While I kind of kept diving in and out of Ubuntu almost from the beginning, Unity really caught my attention and I installed it on one of my multi-boot systems by 12.04 LTS, at first using it for about 20% of the stuff I was doing. A couple of years later that had jumped up to about 30-35% and growing, and by 16.04 it became the main OS on all my systems with a 60%+ usage. Even before 18.04 came along that had reached 80%+!
What caught my attention with Unity was that for once I saw something really innovative - and ambitious - come along in Linux DEs. I now run Unity for mainly sentimental reasons, and it will always have a place somehow. Realistically, a lot of things that once were exciting and innovative, today feel somewhat dated, and I’d really like to see something truly innovative and new coming along again. But still, Unity must not disappear.
