We will see the day your toothbrush has more compute than the original IBM PC.
Pretty sure we have, e.g. [0], "TI's MSPM0Cx MCUs featuring Arm® Cortex®-M0+
core with 24 MHz CPU, 32-bit structure, 4 to 16
KB Flash provide cost-effective designs for electric
toothbrush and shaver applications." - compared to the 5150[1], it's 4x the bus width, 5x the CPU clock, albeit with fewer RAMs.
That insane new Dyson toothbrush definitely. It has on-device AI analyzing 28 fps video from its camera.
