Hey. This is a fair remark and logical too. It's build to run in a sandbox on other OS now to ease uptake. Asking people to install a new OS because "trust me bro" is not gonna work.

That said it is build as an os. It generates real wasm that runs directly on the machine.

Porting to baremetal is next on the backlog. It will require embedding rust cranelift directory into pneuma amongst other things but the hardest/biggest and most architectural part is already done: wasm. You can check out the blog for more info.
