Because man and man-made technology is constantly evolving so rapidly that every new device and new technology also becomes obsolete in a few years and is once completely lost. however, there are a few things i am going to discuss today which we all use now, but in the next 20 years or 20 years they will not be found anywhere else!

Long delivery service

Product delivery services will be much faster and much more reliable in the coming years. now if we buy any product online, it takes at least 1 day in american countries to deliver it at home and also 4-5 days in our country. it takes time. because, all kinds of packages are delivered with the help of traditional shipping methods such as trucks or cars. however, there will be no longer days of long shipping times when shipping companies will arrange for product delivery with the help of drones.

In several US states, Amazon has already introduced experimental drone delivery, which allows a product to be delivered in a matter of hours by drone. Many more e-commerce industries and in the coming years Delivery companies will also arrange product delivery with the help of drones. Hopefully, within a maximum of 15-20 years, drones will become the primary method of product delivery, or a more convenient and faster method than drones.

Wire

One of the most annoying things in the world is fixing a headphone wire. At present, the need for wires or wires in our digital devices has not been raised at all. Speaking of headphones, people are now compared to wired headphones Wireless Bluetooth headphones are the most commonly used, but other devices have not yet become wireless. Many of today's flagship smartphones support wireless charging. However, people still prefer wired charging for fast charging. While wireless mice and keyboards have been available on the market for a long time, ordinary PC users and gamers have always preferred wired devices.

But this will not always be the case. In the next few years, the number of wireless devices will increase more than ever before, as has the case with headphones. People will lean more towards wireless technology, while wireless technology is actually earlier. Will be better and more readily available to people. Not 20 years, it is expected that in the next 10-15 years almost all people will become dependent on wireless devices and the number of wired devices will continue to decrease and at some point will become zero.

Syringe

For those who are afraid to push injections or syringes, this may be the best news. What you may not know is that Healthcare Technology has invented a new type of syringe that has no needles. The name of this injection is “Jet Injection ". Since there is no needle, the patient does not have to feel pain while injecting this syringe. This jet injection is placed over your skin and it injects medicine into your body through a tiny fluid stream. In addition, patients always prefer oral medicine over injections.

So MIT researchers are developing a new type of capsule that will serve as a replacement for injection. This capsule should be taken in the same way as other capsules and this capsule will contain many small syringes that inject medicine into your body. After the capsule reaches your stomach. While this process may sound risky, doctors have confirmed that it is going to be a safe enough process.

Signature

Now all we have to do is use a ballpoint pen and our own name to sign an important document. But along with rapidly developing technology, this signing method is also becoming backdated. If 20 years from now Think about it, then it can be said for sure that then we no longer have to depend on our own handwritten sign to verify our documentation. Because handwritten signatures can be easily copied or forged.

In the future, whenever we need to sign or verify our identity, we do not need to carry a pen. We can use different types of digital methods to verify our identities. To be It could be face recognition or fingerprint recognition or Irish scanning or it could be an overkilled technology like DNA scanning. However, there is no doubt that we will use such advanced technology instead of signatures.

Not only this, there are many other things which will be lost in 20 years and will be replaced in 5-7 years by a new device with more advanced technology. what do you think? and what are the things that will be lost in a few years? you can let us know in the comments section below!
