We can do keyword spotting with microcontrollers now. All kinds of techniques like quantization and tree pruning are squeezing down more capable NLP models further and further. There is dedicated analog hardware being developed for in-memory compute (ReRAM, photonic). TinyML/AIoT is shaping up to be one of the most society-defining technologies of this decade.
