Once Arm and battery life shift occurs with Linux and Windows, they'll (ie. Apple) be on the front foot again with something new, that's the beauty of competition.
This is going to change once Arm on Linux becomes a thing with Qualcomm's new jazz. I am mostly tethered to a dock with multiple screens. I have been driving Ubuntu now for over 4 years full time for work.
I think berrylang shows a lot of promise now https://berry-lang.github.io/. The documentation has improved a lot and while it doesn't have a 'luajit' yet it has a lot of really interesting optimisation/reduction techniques.
