The World in 2050_ Future Technology

From things in the air, to new things for our bodies, join me as we explore 2050: What Would Be The Future Technology?
We are in the year 2020, and if we're being honest with ourselves, technology is incredible advanced, and we're making strides that can push things even farther. We have cars that are much safer than they've been in the past decade, and we're even making fully electric cars that can help save the planet. There are even plans for self-driving cars and even self-driving Ubers that make the future of transportation very exciting. And that's just ONE technology that we're growing at a fast rate. What about all the others that are out there? What will technology be like as we get closer and closer to 2050?
Let's start with one that well and truly could happen very soon, drones. "
Let's keep going with transportation, shall we? Right now, one of the biggest ways to get around the countries we live in are trains. Trains ferry people and all sorts of cargo around in an efficient and reliable manner, which is why they've been in use for hundreds of years. But...if we're being honest here, while trains are efficient and reliable in certain ways...they aren't exactly fast. Especially when it comes to passenger and freight trains. They can take a LONG time to get to their destinations and at times it's more logical to take other modes of transportation.
