  We demonstrate that if consciousness is relevant for the temporal evolution
of a system's states--that is, if it is dynamically relevant--then AI systems
cannot be conscious. That is because AI systems run on CPUs, GPUs, TPUs or
other processors which have been designed and verified to adhere to
computational dynamics that systematically preclude or suppress deviations. The
design and verification preclude or suppress, in particular, potential
consciousness-related dynamical effects, so that if consciousness is
dynamically relevant, AI systems cannot be conscious.
