Why do we need all this digital "things"?
Are we more or less " advanced" then before?
I have few ideas about some of the important inventions which rely upon it.
1. Public key encryption. This allows two people of any rank to securely communicate. Its not easy. It is a little complicated to set up, but you can do it.
2. Finite element analysis. This allows modeling of the weather, so meteorologists can tell you what the weather will be for the next few days instead of only guessing. It relies upon computing, and it saves lives and crops.
3. 3D modeling, CNC and 3D printing. This relies upon computing, and it has the potential to move manufacturing back to families. Family based industries were very much disrupted by the industrial revolution and assembly line. Digital tech has the potential to correct this imbalance of the natural human order.
4. City planning and modeling. Cities can be designed instead of patched together. This can be used for good or evil, but its a good tool. You can make a city that is more pleasant.
5. Traffic and transportation control. This is the key to lowering costs, helping more people live and work together without getting in each other's ways. It uses computer modeling in tandem with city planning and active detection of vehicle traffic which is processed digitally and used to maximize flow. Less time spent in traffic jams equals happier people.
6. Smart phone apps. My favorite app is called Math Tricks, and over the last year it has helped me to improve my arithmetic skills. Its a Math game written by a Russian business (
[email protected]) thousands of miles away. I was able to install this instantaneously for a small fee. My financial transaction was secured through digital encryption technology, so my financial details were protected during the transaction. Electronic reviews and tests for viruses allowed me to measure the risk of installing the program onto my smart phone. The risk was low, and I accepted it, installed the app and then benefited.
7. Medical devices. Electrodes monitor patients for heart problems, neuological patterns etc. Magnetic Resonance Imaging depends upon computational processing of complicated Laplace transformations which would take years by hand and slide rule. Robotic surgeons have turned very invasive surgeries into micro-surgeries, allowing many people to be treated and go home on the same day.
8. Cybernetic limbs. This a new technology is helping people who have lost hands and arms and allows them to have prosthesis that they control with muscle memory.
