> There are lots of folks on HN working on embedded systems. I am wonder what are their thoughts on it? Silicons is already super cheap enough to be used in RFID tags. RFID tags are by far not the simplest ICs around judging by the gate count needed to implement the amount of memory they have, high performance encryption, channel coding, complex clock trees, some are made with quite modern litho, and IP cores of the same grade as Cortex M0.
