An idea is the easy part.
MARQIS started as a simple idea: a small physical device that could be talked to, without a screen. No app to open, no interface to learn — just a box that listens, thinks, and talks back.
That idea took an afternoon to imagine and months to actually build. Between those two points was almost everything worth writing about: the parts that didn't work, the plans that had to change, and the small decisions that quietly shaped the entire system.
This book follows what actually happened in that distance — between imagining the device and building the one that works.
