• 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.
