Some key points from the article:
> Unik pretends to be a Linux kernel, implementing enough system calls to fool the Go runtime.
> The gui program is run with https://gioui.org/
I could see this being useful to write GUI apps that need to run on tiny hardware to reduce the footprint, but the real sweet spot for unikernels I think is backend services. Cool project though!
Another alternative for bare metal Go is TamaGo, developed by F-Secure for their USB armory pen.
Also Nanos - https://github.com/nanovms/nanos for those who want to run go unikernels on gcloud || aws. (I'm involved in the project).
