Award-winning South African film director Donovan Marsh has pivoted to artificial intelligence filmmaking and believes generative AI tools could fundamentally reshape how movies are made – and who gets to make them. Marsh, whose 30-year career includes directing the Hollywood submarine thriller Hunter Killer starring Gerard Butler and Gary Oldman, the Spud films and iNumber Number, is the latest guest on the TechCentral Show. The economics, he tells TechCentral editor Duncan McLeod, are extraordinary: a single complex scene in a traditional production requires crews, equipment, locations and days of scheduling, while AI tools collapse much of that overhead into work that can be done at a desk. But Marsh is clear that the creative work has not disappeared. He still directs shot by shot, much as he would on a conventional set, and uses a patchwork of different AI tools – no single product yet does everything. He has found that simpler prompts produce better results, saying over-prescription tends to degrade out

Everyone agrees that small and medium enterprises are the backbone of the South African economy. But the reality on the ground tells a different story – too many small businesses are still running on spreadsheets and WhatsApp, locked out of the tools that could help them compete. In this episode of TCS+, TechCentral editor Duncan McLeod is joined in-studio by two members of the recently established Vodacom Business advisory board: Sannesh Beharie, managing executive of SME and mobile products at Vodacom Business, and Andrew Fulton, co-founder of data analytics firm Eighty20, a Vodacom Business partner. Vodacom Business set up its advisory board last year to bridge the gap between enterprise-grade technology and the small businesses that need it most, bringing together tech leaders and external specialists to help companies – as well as SMEs – navigate digital transformation. In the conversation, McLeod, Beharie and Fulton dig into what’s actually stopping small businesses from going digital, whether bundled c

MTN South Africa has launched Pi, a digital-only mobile operator that runs on MTN’s network but operates as a standalone brand, offering contract-free mobile and home 5G connectivity through a single app, with no call centres, no credit checks and no lock-in. In this episode of the TechCentral Show, TechCentral editor Duncan McLeod talks to Divyesh Joshi, chief commercial officer at MTN South Africa, about the thinking behind the launch and what it signals about the direction of the local telecommunications market. Pi’s pricing is aggressive: R79/month for 500 voice minutes and R199/month for 20GB of mobile data, for example, alongside home fixed-wireless broadband plans. McLeod asks whether Pi is essentially MTN’s fightback against Telkom, which has been quietly gaining prepaid market share with competitive data pricing – and whether the launch is also a response to mobile virtual network operators like Melon Mobile. The conversation explores what Pi means for MTN’s margins, particularly on voice, and whethe

The South African Post Office has been in business rescue – a form of bankruptcy protection – since July 2023. Business rescue practitioners Anoosh Rooplal and Juanito Damons have made it clear to parliament that the entity will not survive liquidation unless a R3.8-billion bailout is received soon. With some 5 500 jobs on the line, the big question is: is the Post Office worth saving? Rooplal spoke to TechCentral’s Nathi Ndlovu and was asked that question. In this episode of the TechCentral Show, Rooplal talks about: • The case for the bailout: The business rescue practitioners have already received R2.4-billion from government, while bailouts for the Post Office over the past decade amount to nearly R10-billion. Rooplal attempts to answer why this latest funding request is worth it. • The current state of the Post Office: Rooplal outlines what the R2.4-billion tranche was used for and what the R3.8-billion request would do, if provided. He also details what the future state of the entity might look like and

Anton Fatti, chief technology officer of HealthBridge, says the doctor-patient relationship must remain at the centre of digital transformation in healthcare, even as AI reshapes how medical practices operate. Speaking on TechCentral’s Meet the CIO podcast series, brought to you by NTT DATA, Fatti said AI and cloud computing are already easing the administrative burden on doctors and medical professionals, allowing them to spend more time with patients rather than on paperwork and back-office tasks. Fatti joined Healthbridge as CTO in February 2025, bringing experience from senior technology leadership roles at the South African Revenue Service, where he served as chief technology and innovation officer, as well as at Discovery, where he was chief digital officer, and data business Lightstone, where he was CIO. Healthbridge, founded in 1999, positions itself as a technology partner that helps medical professionals run their practices so they can focus on patient care. The company’s offerings have evolved sign

Most security teams can tell you what they've deployed. Far fewer can answer the board's next question: are we actually less exposed than we were three months ago? In many organisations, the gap between security activity and real risk reduction remains stubbornly wide, even as threats become faster, more adaptive and harder to spot. In this episode of TCS+, Clare Loveridge and Jason Oehley from Arctic Wolf unpack what the 2026 Arctic Wolf Threat Report reveals about how the risk landscape is shifting, both globally and in South Africa. They discuss whether organisations are genuinely becoming more proactive, how AI is changing the game for attackers and defenders alike, and why familiar blockers continue to undermine even well-funded security programmes. The conversation also explores what it means to "end cyber risk" in practical terms, why continuous improvement matters more than one-off projects, and how organisations should think about residual risk — the portion that remains even after controls are in pl

Access to stable, reliable, high-speed internet is crucial to participating in the modern economy. Although fibre connectivity offers the highest speeds and reliability, fibre penetration rates unfortunately remain relatively low in South Africa, leaving may would-be customers wanting. Vox recently launched Kiwi, a wireless connectivity solution promising a fibre-like experience with speeds of up to 200Mbit/s. In this episode of TechCentral’s TCS+, Theo van Zyl, head of wireless at Vox, provides more details about the Kiwi service and how it works. Van Zyl delves into: * The rationale behind building a wireless service that offer a fibre-like experience; * Why customers should choose Kiwi over a 4G or 5G fixed-wireless solution; * The technical innovations Vox took advantage of to get the speed and reliability Kiwi offers its customers; * How Kiwi behaves in disruptive scenarios such as thunderstorms; * The various tiers customers can subscribe to and the speeds they offer; * The kind of spectrum Kiwi uses an

In this thought-provoking episode of TechCentral's TCS+, Mpho Chitapi sits down with Dr Josefin Rosén, principal trustworthy AI specialist in SAS's Data Ethics Practice and co-author of the influential report Constraint to Capability: Flipping the Narrative on AI in the Global South. What unfolds is a rich conversation that challenges long-held assumptions about Africa's role in the global AI ecosystem — and reframes governance, ethics and constraint not as obstacles but as strategic advantages. The discussion explores how deeply regulated environments sharpen one's appreciation for integrity, accountability and human impact — principles that are now indispensable in the design of trustworthy AI systems. This sets the tone for a broader conversation on why governance-by-design, representative data and bias mitigation are not "nice-to-haves" but foundational to sustainable AI adoption, particularly for public-facing systems operating in diverse and unequal societies. A central theme is "flipping the narrative"

Artificial intelligence isn’t just changing how work gets done, it’s rewriting the rules of business. Organisations are scrambling to redefine processes and job descriptions, while employees are grappling with new tools and new ways of thinking that are transforming the way they approach their daily tasks. In this episode of the TechCentral Show, Antony Makins, acting CEO at TForge and chair of the special group on AI and robotics at the Institute of IT Professionals South Africa, unpacks the skills revolution unfolding alongside the AI one. Makins delves into the patterns emerging across organisations and the broader labour market as AI adoption accelerates. He also explores the mindset shift it’s imposing on the workforce, and which roles are being hit hardest by AI-driven changes to how we work. He delves into the opportunities that exist despite the very real threat AI poses to jobs – and what government can do to create an enabling environment for workers to adapt to a labour market increasingly shaped b

Safety is a core concern for e-hailing operators as it ensures that platforms engender trust among drivers, passengers and the general public. Bolt recently commissioned market research firm Ipsos to conduct research into the perceptions of rider safety in South Africa's e-hailing market. In this episode of TechCentral's TCS+, Simo Kalajdzic, senior operations manager at Bolt South Africa, discusses findings from the report and how Bolt has used them to inform decision-making regarding its approach to safety on its platform. Kalajdzic delves into: * The rationale behind Bolt's commission of the report; * Why market research firm Ipsos was chosen to conduct the research; * Key findings from the report and the products Bolt has developed using those insights; * The key drivers fuelling e-hailing adoption in South Africa and where safety ranks compared to other factors like reliability and cost; * Scenarios that lead to South African's choosing e-hailing over other transport types; * How e-hailing compares to ot

Technology sits at the heart of modern capital markets, and nowhere is that more evident than at the JSE. In the latest episode of Meet the CIO, TechCentral editor Duncan McLeod sits down with Tebalo Tsoaeli, the bourse’s CIO, to unpack how technology underpins Africa’s largest stock exchange – and how it is evolving for a more digital, global and real-time future. Meet the CIO is brought to you by NTT DATA, where global experience meets local impact. Tsoaeli has spent his entire career in financial services technology, starting out as an application developer at Rand Merchant Bank before holding senior technology roles at Standard Bank, Investec, Nedbank, FirstRand and Sanlam. He became CIO of the JSE three years ago, bringing deep experience in large-scale, mission-critical systems to one of the most tightly regulated technology environments in the country. In the conversation, Tsoaeli reflects on his early exposure to computing and how a formal grounding in computer science shaped his career path. While he

The cloud revolution has challenged businesses of all sizes by changing how IT teams go about implementing projects and managing infrastructure. IT service firms have been doubly challenged, having to sell a new computing paradigm to their clients while also practising what they preach and adopting cloud-first technologies in-house. Consnet is an IT solutions firm that leveraged the Amazon Web Services distribution model to accelerate its own journey into the cloud, enabling the company to do the same for its customers. In this episode of TCS+, Dion Kalicharan, MD at Consnet, and Xhenia Rhode, AWS partner development manager at Cloud On Demand, speak about the benefits of leveraging the support structures in the AWS partner network. Rhode and Kalicharan delve into: • What the AWS distribution model is and how it benefits partners in the ecosystem; • Consnet’s 21-year history, the services it provides and how its journey into the cloud began; • How Consnet being supported by Cloud On Demand gave it the know-ho

TechCentral’s electric car show Watts & Wheels is back for episode 3 of season 1, and while EVs remain the focus, the conversation takes a detour into something far less planet-friendly – and far more jaw-dropping. Duncan McLeod and co-host William Kelly kick off by drooling over a wild new Toyota performance machine they say is real, street legal and due in 2027. It’s a 4l hybrid V8, rear-wheel drive “hypercar” with supercar proportions and serious numbers: 478kW and a quoted top speed of 320km/h or more. It’s the sort of car that feels entirely out of character for Toyota – and that’s exactly why they can’t stop talking about it. From there, the conversation swings hard in the other direction: the all-electric Porsche Cayenne, which is shaping up as a huge statement from Stuttgart. The hosts discuss its performance claims – including a 0-100km/h sprint in the mid-2s range – and a range figure north of 600km. They also debate the realities of EV depreciation and whether buyer anxiety around battery longe

Chinese car makers continue their rapid push into the South African market, raising uncomfortable questions for incumbents. With aggressive pricing, fast product cycles and increasingly polished vehicles, the competitive landscape is shifting faster than many expected. There is also an update on Stellantis’s manufacturing plans and what they could mean for South Africa’s position in global automotive supply chains. The discussion turns to plug-in hybrids, which are emerging as a key battleground. The Omoda C9 PHEV and Haval H6 GT PHEV are discussed as examples of how Chinese brands are targeting buyers not yet ready to go fully electric. Duncan and William chat about two new vehicles in South Africa: the Leapmotor C10 (and why William hates the term REEV) and the Alfa Romeo Junior Elettrica (which William is prepared to give a kidney to own). And then there’s the Toyota GR GT. Duncan explains why this supercar has him seriously questioning his principles – and why some petrol cars are still capable of making

South Africa’s automotive industry is in a state of flux. In this episode of the TechCentral Show, BMW Group South Africa CEO Peter van Binsbergen unpacks the challenges – and opportunities – facing a sector under pressure. He tells TechCentral editor Duncan McLeod about the future of BMW’s Rosslyn manufacturing plant in Pretoria, which was established more than half a century ago, and the urgent need for new government policy to ensure the automotive industrial base in South Africa is future-fit and ready for the shift to electric mobility. Van Binsbergen also discusses the rise of imported vehicles in the sales mix in South Africa – including the rapid expansion of Chinese brands. China is a market he knows well, having spent three years there with BMW. In the interview, TechCentral Show viewers will also hear about: • The state of the local automotive manufacturing industry; • What South Africa needs to implement in policy reform to ensure the automotive industrial base in South Africa – and why this is ur

Cybersecurity is undergoing a quiet but important shift in South African boardrooms: from a defensive cost centre to a strategic business enabler. That was the central theme of a recent TechCentral TCS+ podcast discussion featuring Vodacom Business acting executive head for cloud security Lukhanyo Zahela and KnowBe4 Africa senior vice-president for content strategy Anna Collard. Once seen primarily as an IT problem, cybersecurity is now recognised as a material business risk with direct financial, operational and reputational consequences. But the discussion made clear that security, done well, can also signal organisational maturity to regulators, investors and partners – and increasingly, become a source of competitive advantage. Collard likened strong security controls to having “good brakes on a fast car”. Without them, businesses cannot safely deploy emerging technologies such as artificial intelligence or scale digital platforms with confidence. Availability and resilience, she argued, are foundational:

TechCentral’s motoring show, Watts & Wheels, is officially back, with the first full episode of season 1 widening the lens beyond new cars to look at the forces reshaping South Africa’s automotive industry. The first episode of season 1 – you can catch our “season 0” episodes here – opens with a sharp focus on South African Auto Week, where the pressure on local vehicle manufacturers dominated discussions. Original equipment manufacturers are facing a tough balancing act as imports rise while local assembly plants wrestle with costs, scale and uncertainty. From policy to products, the show then shifts gears to tyre maker Bridgestone, which has launched new tyre offerings for the South African market. In an interview, Jacques Rikhotso, CEO of Bridgestone South Africa, unpacks how changing vehicle technologies – including heavier EVs – are influencing tyre design, durability and safety. Chinese brands also feature prominently. A dramatic crash test involving the Chery Tiggo 9 Pro highlights the rapid stride

Africa’s digital transformation continues to accelerate, driven by growing cloud adoption and rising interest in artificial intelligence. Yet many organisations still face challenges in converting these ambitions into measurable business outcomes. According to Cliff de Wit, group chief innovation officer at Accelera Digital Group, the success of AI-driven initiatives depends as much on culture and governance as it does on technology. In this episode of TechCentral’s TCS+ podcast, De Wit outlines the practical steps leaders can take to reduce organisational friction, strengthen data foundations and enable cloud-led innovation at scale. “Cloud is no longer an IT decision. It is the foundation on which every modern AI strategy is built,” says De Wit. And technical readiness alone is not enough. “The biggest barrier is not the tech, it’s whether the organisation is prepared to manage change at the pace AI requires.” In this episode, De Wit discusses: • The concept of organisational drag and how it affects AI prog

Newly minted small businesses often struggle to establish themselves as reliable service providers among their more established competitors. To help cloud-focused business thrive, Amazon Web Services has created the AWS distribution model to support small businesses and help them grow. In this episode of TCS+, Cloud on Demand’s Xenia Rhode and Developmenthub’s Odwa Ndyaluvane explain how the AWS distribution model benefits partners in the same ecosystem. In this episode, Rhode and Ndyavulane discuss: • An overview of the AWS distribution model and its ecosystem partners; • Who Developmenthub is and how the company started; • The support Cloud on Demand, an AWS select partner, provides to Developmenthub; • The business outcomes that Developmenthub has achieved through the partnership; • The business development support available within the partner ecosystem; • The new market access opportunities Cloud on Demand was able to avail to Developmenthub; and • New revenue streams that Developmenthub was able to tap

South Africa’s big three telecommunications operators have all reported numbers in recent weeks, and the theme is clear: competition in prepaid has intensified sharply. Telkom’s resurgence has put pressure on both MTN and Vodacom, with MTN acknowledging it has “discernibly” lost prepaid market share. This is one of the topics covered in this wide-ranging and exclusive TechCentral Show interview with MTN Group CEO Ralph Mupita, who sat down earlier this week with TechCentral editor Duncan McLeod to discuss this and other major topics, including: • The impact of online gambling on the telecoms sector; • The need for further consolidation in South African telecoms, and why Mupita won’t completely rule out a deal with Telkom, provided the “stars align”; • Vodacom’s acquisition of a co-controlling stake in Vumatel parent Maziv and how MTN will respond; • The impact of low-Earth orbit satellite connectivity on the telecoms industry and how MTN plans to work with companies like SpaceX/Starlink and Amazon Leo – and w
