Scala Native [1] has been really quiet of late (last commit July 29), not sure what's going on. There was a lot of excitement when the project kicked off, hopefully it continues to evolve.
Yeah I figured that was the case. There is a lot of steam behind native-image with graal/substrate though.
Yes the user community seems to think that GraalVM can do whatever Scala Native can.
The creator and lead contributor has been finishing up his school but I am not sure of his plans for the future. There is a book coming out on the subject, https://pragprog.com/book/rwscala/modern-systems-programming... and I am hoping it will continue to grow and evolve.
