The promise of the so-called ‘malleable computer’:

a machine whose hardware parts you could change, as well as bigger chunks of its software, above and beyond end-user apps. That is possible via the integration of the OS with AI agents that do the heavy lifting for you in adapting the OS to your ‘needs.’ Users of the Pi coding agent get a better feeling for this because the tool is, by design, built to respond and adapt to user-commanded changes. This is the kind of capability the typical user won’t see in private-source OSes like Windows and iOS, especially because they have security as a concern (thus the OP’s motivation for the heads-up on security in Omarchy).
