We have rotten tools. At best they give us only a crude analogy about our code. The future holds more visceral visualizations.
The advancing complexity in consumer electronics is posing serious challenges for designers and users alike. Key to managing this complexity is the intelligent use of embedded systems.
Some people say that embedded devices have such a unique relationship with servers that they need their own top-level domain. Is there a .emb in your future?
