So an OS that’s lets user operate very close to metal/driver level? I still can’t imagine what the os will look like vs regular Linux

It doesn't have a GUI so it doesn't 'look' like anything other than a way to define new FORTH words and some basic low level drivers.

It does have a GUI. Not much is written for it yet, though

That's not a GUI. That's barely a display driver.
