Web 3.0 is all about connectivity. Connected data, connected intelligence, and also connected people. Web 3.0 aims to automate things through connections. Your refrigerator will one day be connected to the market to order whatever you are out of, Your personal fitness will be tracked and connected to your doctor, your PC will recommend things to you, and as a whole, your life will be connected. This, however, creates more risk and vulnerability to hackers, as many believe that your data will be more important than your actual possessions. Web 3.0 will be a wonderful thing, but will collectively be much more dangerous.
