Technology to Turn our minds into Supercomputers
Imagine a time when the blind will be able to see, the deaf to hear, the disabled will be able to walk, people with brain disease will be cured, and people will have computer-like mind power. This might seem like science fiction, but is going to be a reality in the near future.

Video gaming is BIG business
Which country has the most video gamers in the world? Hint: not the USA. Video games are BIG business globally, with billions of dollars of annual revenue. The big question is, are video games the cause of violence, like the El Paso shootings in the USA in 2019, or is it all just media hype? #technology #videogames #violence #massshootings

Incorrect Perceptions about Smart Cities
South Africa is long overdue for Smart Cities Last  week I was invited to speak on the Economics Unbound programs on the SABC Live News channel. The topic was Smart Cities, and we discussed  various aspects, primarily whether President Ramaphosa’s vision for a  South African Smart City was realistic, and whether South Africa was ready for a Smart City.  Based  on the feedback received via social media, it became clear that the  general sentiment among South Africans on the topic of Smart Cities was  negative. However, most of this negativity stems from misconceptions many people have about smart cities

Rise of the megacities
We are living in a time when the world’s population is experiencing accelerated growth. According  to the study, by the end of this century 25% of the earth’s population,  which will hit the 13 billion mark, will reside in urban areas. This  will give rise to cities that will be much bigger than anything we’ve  seen in human history: cities I like to call mega-mega cities.

How cities are becoming smarter
In 2006, for the first time in  human history, the number of people living in urban areas equaled the number living in rural areas. This was due to what is often labelled as  the “biggest mass-migration in history”, where the world’s population is moving in masses away from rural areas into urban areas. Naturally, this increase in population will place tremendous amount of pressure on the infrastructures of the world’s cities like public transportation, water supply, power supply, sanitation, solid waste management and others.

Don’t dismiss President Ramaphosa’s smart city idea
The recent announcement by President Cyril Ramaphosa about developing a  “smart city” in South Africa has created quite a stir and has triggered a  lot of conversation. Unfortunately, it seems not many people are  thrilled about the idea.

Retail Genesis
Naseema Adams has had enough. She has decided to close her women’s clothing store after four years in operation.   “The rentals and operating costs are insane. It’s just not worth it anymore,” she says.  Naseema has decided to become part of a global movement that is taking the world by storm: she is joining the ranks of what I call the “micro-e-entrepreneurs”.

Why is online retail taking over?
In the previous episode, we spoke about the impact of ecommerce on traditional brick-and-mortar stores. But why is ecommerce so successful, and why is it taking so much away from traditional stores?

The Retail Apocalypse
The  ongoing “retail apocalypse” in the United States has claimed more  victims in the first quarter of this year than all of 2018 combined. By  end April this year, almost 6000 retail stores closed down in the US, while the total number of store closures in 2018 was just 5864. This  a continuation of a trend that has been going on since 2010, and rather  than slowing down, it is only showing signs of accelerating.  Researchers predict that by 2026, nearly 75000 stores will have closed  down in the US alone. What is causing this this apocalypses and should we try and stop it?

Cryptocurrencies  have gained a lot of negative publicity recently, due in large  part to their wildly volatile prices, but also due to reports  of cryptocurrency theft to the value of over US$ 1 billion in 2018  alone. This is particularly alarming for a currency that was touted as  being blockchain-based, and hence super-secure. I have nothing against  cryptocurrencies; I believe they are great in theory, even though they  do have some unresolved issues. But in time, they might evolve to a  point where theory becomes a practical reality.

How Blockchain can revolutionize the vehicle industry
Imagine if there was a database that collected and stored information about every vehicle on the road, from the time of it's manufacture to the present moment. This database would track every transaction that took place relating to the car. By simply entering  the chassis number, you could get access to minute details about the vehicle’s manufacture, its previous owners, its service and maintenance records, records of any accidents it has been in, and a host of other pertinent info. Thanks to blockchain, this technology could be a reality.

Blockchain and Bitcoin are not the same
Let me start off by clarifying a huge misconception: the blockchain is not the same thing as Bitcoin. They are two very  different technologies, even if they are somewhat connected.

Can South Africa catch up technologically to the rest of the world or is it to late?
It was with great excitement and enthusiasm that I learned about your decision to set up a presidential commission on  the fourth industrial revolution. I believe it is a positive step in the right direction for our country, even though many people say it is  too late.

Should tech companies share their technology with militaries?

A Battery Operated World
The energy situation in South Africa is unsustainable, and it is not just the poor and working class who are suffering; the entire economy is feeling the pain, and it is just a matter of time before it reaches the verge of collapse, unless we do something about it urgently. Fortunately, there is hope on the horizon or, more accurately, in the sky.

New plastic recycling process
Ever  since its invention by Leo Baekeland in 1907, plastic has transformed  our world in countless ways. It is simply not possible to imagine a  world without plastics: everywhere you look, you will find plastics. But what was a miracle for us, has turned out to be a disaster for the environment. Is it too late or can advancements in technology prevent a possible ecological disaster.

What are Social Media Networks Doing to Prevent the Spread of Hate Speech?
When  Mark Zuckerberg started Facebook in 2004, there was no way he could  have known that his little website was going to become the world’s most  popular social network with nearly 2 billion registered users. He also  could not have known that his social networking site would be  instrumental in one of the most heinous crimes committed in the past century.
