@bengy thanks for doing these it is always fun to read through these and try and give a good answer. That being said I a going to go with something that I think will be new to most and not to all. That is the new 5g wireless networks. People talk about the internet and what is has done for the world but at the same time they don't all realize how many people are not on the internet and even more how many don't have fast internet. Right now it is estimated that about half the world doesn't have access to the internet and of the half that do some are still restricted to what they can view. Those users at force to try to find away around those firewalls that make they fall back on slow wireless internet. Well that could be a think of past soon. "Verizon hasn't specified how fast its 5G network speeds will be, an early test witnessed by CNET showcased whopping speeds of 3.77Gbps. " source Right now even in many parts of America people are on internet speeds under 20 Mbs. Why cause we are very bad at upgrading our infrastructure and most areas only have old copper wires and the only areas with fiber are major cities or places google or amazon had it installed. Now Verizon isn't the only person doing this. You can read a lot here But Facebook and Google along with a few others are looking to use this kind of wireless internet to connect people all over the world. This will lead us to a truly interconnected world. With speeds that would allow you to video chat with people in countries to you might never get to visit in person. This is going to change the world and it is going to do it soon.
