Why the future of IoT depends on open source

Most people are familiar with the Internet of Things (IoT), which refers to smart objects in a connected network, as this diagram shows. A "smart" object has a sense of its environment, and it makes decisions (locally or together with peers and a cloud server), then puts those decisions into action. To be smart, the object must have a brain to carry intelligence. So far, the way to do this is to embed a computer in the object. For example, you can put a Cortex-M CPU with Bluetooth 5.1 in a chip smaller than 2x2mm and embed it into almost anything.
