The Connected World
A World that Senses, Computes, and Acts
The Final Loop
We have built circuits, written code, launched satellites, spun up neural networks, and secured servers. Now, computation leaves the screen and enters physical reality. The Internet of Things is the culmination of the DCIO sequence: embedding intelligence into the physical environment to close the loop between sensing and action.
