It seems pretty unlikely that unikernels will ever replace containers.

Containers allow you to run almost all of the past decades of software with no or little modification (and most modifications are done in bash), a unikernel is more like a new OS that applications need to be ported to, without the full POSIX API (eg, no subprocesses) - it's probably easier to port a multiprocess server (eg most SMTP servers) from Linux to the NT API than to port them to a unikernel

Not necessarily, on programming languages with nice standard libraries/runtimes it is just a matter of running them bare metal.

A JEE application doesn't care if WebSphere is running on OS XYZ, bare metal or an hypervisor.

In a way I consider POSIX C's runtime that should have been made part of ANSI C.
