This is a neat writeup. I think the ESP32, alongside similar microcontrollers that tie communication via complex protocols so close to direct interaction with the physical world for such a small energy cost, are really amazing for teaching, inspiring, and empowering otherwise "non-technical" people. Of course, you do have to be able to program, but I think we're making great strides in making that as easy as possible with things like CircuitPython and EduBlocks.
Also, this kind of shocked me:

Those cards are way too expensive to be lacking such a useful feature!
