Abstract: A domain-specific hardwired symbolic machine is disclosed that processes information via the flexible formation and hardwired mapping of symbols from one or more domains onto other such domains, computing and communicating with improved security because it has no CPU, no Random Access Memory (RAM), no instruction registers, no Instruction Set Architecture (ISA), no operating system (OS) and no applications programming. The machine may learn, e.g. from its users, via hardwired analysis of domain faults with associated recovery. The machine may modify itself according to interaction with its authorized authenticated users with self-modification via learning within application-specific, user-specific constraints hardwired into the original machine, eliminating configuration management and computer programming.
