Unikernels: No Longer an Academic Exercise?

So in the server less future, Linux and FreeBSD will no longer be at the heart of these "Functions"? But instead they all migrate to Unikernel? At the scale they are operating I am pretty sure it make sense, if it brings 5 - 10% performance improvement along with other benefits.

Not sure if I like the way things are moving in that direction though.

In a way, POSIX is the C language runtime, and other languages have their own runtimes as well, so at the limit whatever kernel your application is running one doesn't matter at all.

Then there are those few use cases where one actually needs to dive into OS specific syscalls or Assembly.

So for a large class of applications it doesn't matter if the application is running bare metal, on a VM, container or plain old OS process.
