Technologies that would Revolutionize 2021

Future tech - Chris Skinner's blog
We are in the middle of 2020  - the year of high hopes and massive letdowns and there's no better thing to do than hope for a pandemic-free 2021. In view of this, we have looked up interesting stuff that is planned for 2021 and there are many that could get you exciting. From Smartphone tech all the way up to space missions, various topics are covered here. It's almost as if we made a leap into the future and came back like in the movie - Back to the Future ( If you haven't watched it , you should definitely do so!) 

1. Exoscale Supercomputers Get Deployed : 

Super computers are generally ranked on their performance in executing FLoating point OPerations (FLOPs). If you're wondering what floating point operations are , they are basic addition,subtraction,multiplication and division operations done of numbers with decimal points. It may seem counter intuitive as to why this is considered as metric to judge an Ultra Fast Super computer. Well, the fact is computers take the maximum time to perform these decimal point operations though they may seem trivial to us humans.

There are complex hardware components designed specially to handle these tasks. Now, that we have established FLOPs , if you prefix the term "Exoscale" to it , suddenly there a ton of zeros added to the number. To be clear, 1 Exoscale or Exoflop is equal to a 1 million trillion or 1 quintillion which is1,000,000,000,000,000,000 FLOPs per Second! The current speed achieved is just one zero less than the Exoflop ie 10 to the power of 17 FLOPs per second. So, in 2021 the Supercomputers would be 10 times faster than the Supercomputers in 2020. How cool is that ! 

2. Global Internet Traffic Reaches 222 Exabytes : 

Continuing the trend of "Exa" from previous point, it's predicted that Fixed Internet Line Usage would peak at 222 Exabytes per Month while the Mobile Internet Usage would peak at 57 Exabytes per month.

The current statistics are 174 Exabytes per month and 41 Exabytes per month for Fixed Internet Line and Mobile internet usage. That is 27% jump in the internet usage  per month globally. In 2011, the usage was about 30 Exabytes per month which would mean in just 10 years the internet usage has grown exponentially to 7 times !

3. World's first Air Taxi would be Launched in Singapore : 

Volocopter and Skysports had Introduced the concept of Air Taxi this year loaded with modern features like biometric checkin, electric take off landing, facial recognition, and many more. The docking stations would be called as "vertiport" and could cover distances of upto 30 Kms initially. The Taxi's offer an autonomous and pilot version of Helicopters as part of the Air Taxi ride. The Taxi could accommodate 2 people at the time with luggage and can cover maximum distance of 30Kms in radius. The logistical part of the transport are expected to be in place by the end of 2020 for the official launch in 2021. Other companies like Uber, Boeing, Airbus are also planning to launch similar modes of public transport services in Singapore. Have a look at this futuristic video

4. 5G connectivity to be introduced in Major Cities in Canada and USA :
With 5G being officially deployed in China and some parts of USA and range of smartphones offering the support , the 5G wave seems to launch off the pad finally in 2020. 
Samsung Selected as 4G LTE-A & 5G Network Solution Provider by ...

Well, in 2021 it's expected to ramp up exponentially and start scaling out to other industries like Pharmaceuticals, Automotive , Medical , Real Estate, Manufacturing , etc. By the end of 2021 , it's expected that all the major cities would be covered with 5G and the smartphone prices are expected to drop at the same time with increasing demand and sustained production line. 

5. Ethereum Deploys Casper and Sharding Protocol :
As most of you would have heard about Ethereum in some conversation or others, what you might not have heard is about the 2 new protocols in pipeline. Ethereum is a cryptocurrency that currently works on POW(Proof of Work) protocol where each crypto miner has to prove he has solved the "mining" puzzle. When the miner solves the puzzle he adds a block in the network and every time a transaction goes through his block , he gets a commission and that commission is the Bitcoin. But, the trick here is the solving of the puzzle which is series of mathematical operations is too tough and energy intensive that the return on investment is negative.

With the Casper protocol which works on POS (Proof of Stake) process, each person who solves the puzzle can bet on a block that gets added to the network and he has to bet it with some number of bitcoins himself. This completely eliminates the competition for the block as it is chosen by the Casper algorithm based on the bet placed by the miner. This protocol is set to revolutionize the Cryptocurrency scene and greatly reduce the cost and network burden with fair competition. 

2021 looks to be promising , if we minus out the pandemic implications and looks to be the 2020 we were promised! One way or the other these technologies will be introduced and are definitely in the category of high impact. You would soon be hearing these in the news and quite possibly be the users of the same. Let me know how excited you are for these Futuristic Tech !

Don't think about Buying Tablet in 2020! They are going to be Dead!

Remember the time when the "mobile" phones were not "smart" yet and had this really compact form factor with durability such that they can only be destroyed by some natural calamity ? Yep, those times were not far from today ..just a decade ago and we didn't have to think about the phone falling off a cliff, or catching fire or trampled under a car or drowned into a sea! Then there was this highly delicate and expensive loner phone called the "iPhone" which required such extreme care, for you wouldn't be able to afford its maintenance! This phone was one of the first ones to start a trend of increasing the display size over the year and that led to hilarious memes as below Being mocked by their competition only strengthened their move and Apple went onto release the iPhone 11 Pro Max or Max Pro (whatever!) which was 6.5 inch long and was close enough to the prediction in the memes. This time it wasn't getting mocked but was

How to Pair Huawei Watch GT2 with Any Headphones within 1 min - the Perfect Hack

The Smartwatch and wearables industry has seen the biggest spike in 2019-2020 time frame. Starting off with Apple Airpods to may other brands trying to mimic the design and provide low cost alternatives the users have graciously welcomed each and every product in the line. There is a fan base for the neckband type, another base for the "TWS" (Truly Wireless) Earbuds and there's altogether separate base for the Wireless Headphones category. Then we saw an upsurge in the health monitoring wearable devices which was popularized by Fitbit and then in the last couple of years by Apple and Xiaomi. The current market has many players and there's no clear winner in terms of market share for the smartwatches / health monitoring wearables. Huawei has somehow missed the train and joined in late for the party. But as they say in Hindi - " Der aaye Durust Aaye .. "  which means - Came in Later But in a mint condition .. Huawei launched its first smartwatch the

Sony Xperia 1 II - the Lazarus of Smartphones

Well, well, well... Look who's back on the Street ! He's tall ..he's strong..he's Loaded ! That's exactly what the Xperia 1 II is all about ! Sony can well be termed as the "Lazarus"  for coming back from the dead - quite literally. It was standing against all the odds with likes of Samsung, Apple, One Plus in Premium and Xiaomi, Oppo, Vivo, Huawei in the Mid Segments, Sony had no where to land and with this particular model they have reaffirmed their faith in their Premium segment and its definitely Working ! I know the naming is weird (seriously who names their product "one" "two" ) Check out their official Video: Credits : Sony Youtube Channel Credits : NDTV Mind you , this is the first smartphone with a 21:9 4K HDR OLED 6.5" Display with 90 Hz Refresh Rate - let that sink in. Sony has used its experience in its Television Display tech and dropped it straight up on the Xperia 1 II. With the notch nicely hid
