    TCS+ | Why South African workers must become supervisors of digital labour

    ADG’s Cliff de Wit on why the next management challenge is overseeing teams of autonomous software agents. Not long ago, organisations were experimenting with generative AI to draft e-mails, summarise documents and answer questions. Today agentic AI is changing what the technology is for. In a conversation on TechCentral’s TCS+ podcast, Cliff de Wit, MD for South Africa and group chief innovation officer at Accelera Digital Group (ADG), argued that the real story is not machines replacing people but a fundamental shift in how work gets done — and where humans create value. Rather than completing individual tasks on command, AI agents can be given an objective and left to determine how best to achieve it. De Wit illustrated this with a know-your-customer (KYC) use case in which agentic AI is already automating complex workflows and accelerating business outcomes. AI is no longer simply a tool that assists workers. Increasingly, it is a digital workforce in its own right. In a country with one of the world's highest youth unemployment rates, concerns about automation are understandable. But De Wit challenges the idea that AI should be viewed purely as a job-replacement technology. "The human skills involved in business are fundamentally changing, but the basics of business still remain," he said. Businesses will still need people to solve problems, exercise judgment, build relationships and drive innovation. What changes is how those outcomes are achieved: as routine and administrative work is automated, workers move up to activities where uniquely human skills matter most. The sharper risk is distributional. Without investment in education, training and digital skills, AI's productivity gains could widen existing inequalities — not because jobs disappear, but because opportunity concentrates among those who know how to work with the technology. AI literacy may soon matter to employability as much as computer literacy did during the digital revolution. Organisations are already deploying agents into operational environments, in some cases slotting them into workforce structures alongside human employees. Leaders are no longer managing only people; they are managing mixed teams. De Wit believes businesses are better prepared for this than they think. Companies have long used governance frameworks and risk controls to oversee human decision-making, and many of the same principles adapt to digital workers. Whether a decision is executed by a person or a system, accountability, escalation and oversight remain essential. Which decisions should be delegated, then, and which should stay under human control? De Wit's answer comes down to risk, and he sets out a framework for categorising it. The future, on his reading, is unlikely to be fully autonomous. Successful organisations will run human-in-the-loop models in which AI handles execution while people supply direction, judgment and accountability. De Wit is optimistic. Many local organisations are still experimenting, but a growing number are moving past pilots to solve real problems and generate measurable value. For leaders, the question is no longer whether to adopt AI, but how to do so responsibly, effectively and inclusively. The future workforce will consist neither solely of humans nor solely of machines — it will consist of humans who know how to lead, govern and orchestrate digital labour. And that future is arriving faster than many realise. Don’t miss a great discussion!

    Icasa's rules skip the real bottleneck: ACT

    Communications regulator Icasa’s draft rapid deployment regulations – a critical intervention for the sector – risk failing unless the regulator brings municipalities into the process, according to Nomvuyiso Batyi, CEO of the Association of Comms & Technology (ACT). Speaking on the TechCentral Show with TechCentral editor Duncan McLeod, Batyi said Icasa had consulted network operators and fibre companies but not the South African Local Government Association, which represents the municipalities that will have to apply the rules. “You cannot just develop regulations without talking to all the parties,” she warned, arguing that Icasa should follow energy regulator Nersa’s approach to municipal engagement. Asked when final rules might realistically be in place, she said 24 months – provided Icasa works through local government first. On enforcement she was more optimistic. Section 21 of the Electronic Communications Act, amended in 2014, already empowers Icasa to set uniform procedures for permits and approvals at a reasonable fee, she said. “A lot of people may have missed the amendment.” The gap is dispute resolution: the draft assumes disputes between licensees, leaving operators without recourse when a municipality refuses a way leave. At Icasa’s public hearings this month, ACT proposed binding municipal deadlines, deemed approval and damages claims for failing to respond to requests in time from telecoms providers. ACT also objects to the detail in Icasa’s proposed national infrastructure database. Batyi supports mapping in principle but said the granularity sought would expose competitively sensitive information and create construction mafia and cybersecurity risks. Beyond rapid deployment, Batyi listed four priorities on her plate: the newly finalised Rica framework agreement on Sim card verification, licence renewals by 2028, Icasa’s end-user and subscriber charter regulations and the Electronic Communications Amendment Bill – which she described as “embarrassing” in its current form. ACT represents Vodacom, MTN, Telkom, Cell C, Rain and Liquid Intelligent Technologies. – © 2026 NewsCentral Media

    How Optasia lends billions to people banks can’t see

    Optasia is on target to distribute more than US$6-billion in credit across its markets in 2026 – and it carries every cent of the default risk itself. In this episode of the TechCentral Show, CEO Salvador Anglada unpacks how the JSE’s biggest recent fintech listing actually works. Formerly known as Channel VAS, Optasia was founded in 2012 as a single-country airtime credit provider. It listed on the JSE main board on 4 November 2025 at R19/share – top of the range, and oversubscribed several times. FirstRand took a 20.1% stake ahead of the IPO and has since raised it to 26.1%. Today, Optasia’s AI-driven credit decisioning platform operates in 38 countries through mobile operators – MTN and Vodacom among them – and financial institutions, serving more than 120 million monthly active users and making 1.5 billion credit decisions a month. Microfinancing now generates 72% of revenue, overtaking the airtime advance business on which the company was built. In the interview, with TechCentral editor Duncan McLeod, Anglada discusses: • What happens in the 30 seconds it takes an unbanked customer in Accra to get a loan – and why partner banks, the “lenders on record”, carry none of the risk; • The algorithms behind it: more than 5 000 data points per customer, models tailored to each market and a blended default rate of just 1.2% on unsecured loans with no collateral – and no blacklisting of defaulters; • Optasia’s plans for South Africa, where Anglada sees 15-20 million people without proper access to credit – and why local banks will be the channel; • The Nigerian regulatory dispute that suspended its airtime credit services – a suspension Anglada calls “a little bit aggressive”; • Why Optasia chose the JSE over London, and how it works with FirstRand; and • The road to 2030: new markets including Ethiopia, Egypt and Mozambique, plus SME lending, buy now, pay later and a “virtual credit card” now in testing. Optasia reports interim results in September, with revenue guided up by more than 50%. Don’t miss the discussion!

    Pick n Pay’s Enrico Ferigolli on Penny, the AI that shops for you

    Pick n Pay has switched on an AI shopping companion called Penny inside its asap! app, and in this episode of the TechCentral Show, retail executive for omnichannel Enrico Ferigolli takes editor Duncan McLeod through what it does and why it matters. Built on Google's Gemini models, Penny lets customers build a grocery basket by asking for what they want in their own words – by voice, text or photo – instead of searching and scrolling. Tap the "Ask" button, request a carbonara recipe, and Penny returns the method alongside a carousel of options for each ingredient to drop into the basket. It handles re-orders, meal planning to a budget and ingredient substitutions, and it reads photographs, too: Ferigolli describes snapping a handwritten shopping list and having Penny build the basket from it. In the conversation, Ferigolli is candid about the limits. Penny does not place orders yet – it assembles the basket and hands the customer back to checkout – and its language support, while broad, is stronger by voice than by text and still maturing for South Africa's African languages. He explains why Pick n Pay tested several large language models before settling on Gemini, how the system draws on the app's own search, order history and Smart Shopper data rather than plugging Gemini straight into its databases, and where a retail-media layer fits in. For more detail on the launch, see TechCentral’s full report on Penny and how it works. Ferigolli discusses: • How conversational shopping changes the asap! experience • Why Gemini won on accuracy, speed and cost • What Penny can and can't do at launch • The multilingual and multimodal ambitions behind it • How the 2025 asap! rebuild set this up, and what comes next Pick n Pay is "a little bit behind" in online grocery, Ferigolli concedes in the podcast – but with Penny and the features to follow, he reckons it will "get ahead really, really fast".

    Charge’s R1.8-billion bet on an off-grid EV future

    South Africa has fewer than 400 public electric vehicle charging stations – up from zero just 15 years ago – and EV adoption remains stubbornly slow. Yet Charge, formerly known as Zero Carbon Charge, is betting big that a coast-to-coast network of off-grid, renewable-powered charging stations is exactly what’s needed to fire up the local market. In this episode of the TechCentral Show, Joubert Roux, co-founder and director of Charge, joins TechCentral’s Nkosinathi Ndlovu to make the case for the company’s ambitious, R1.8-billion plan to roll out a charging station every 150km along South Africa’s national highways – and to explain why he believes the company is taking on “a timing risk, but not a business risk”. Roux walks TechCentral through the December 2024 launch of Charge’s first site near Wolmaransstad and the unit economics underpinning the roll-out: just seven vehicles a day at each station are needed to reach Ebitda break-even. He also explains why every facility is designed to operate entirely off-grid, citing data showing that EVs charged on Eskom’s coal-heavy network emit 5.8 tonnes of carbon-dioxide a year, more than a comparable petrol car at 4.4 tonnes. The conversation also tackles Charge’s unconventional fundraising strategy: a tokenised public offering on Mesh rather than a JSE listing, planned for June 2026. Roux argues that South Africa’s institutional capital is “extremely conservative” and that tokenisation will finally let ordinary investors into an infrastructure deal that has historically demanded R1-million minimums. The Development Bank of Southern Africa has already committed R100-million. Roux and Ndlovu also discuss: • How landowners hosting Charge stations receive 5% of charging revenue, and the rural economic development case that sits behind that model; • The offtake agreement with transport aggregator Zimi covering 50% of capacity at upcoming N3 corridor sites; • Charge’s formal objection to Sanral’s proposed policy giving it powers over businesses within 60m of national roads or 500m of interchanges, and the broader regulatory headwinds facing EV infrastructure; • How BYD’s planned 1MW supercharger network and incumbent operators like GridCars – which already records 5 000 charge sessions a month – are reshaping the competitive landscape; • Plans for 35MW truck-charging facilities and a long-term target of 120 stations across the national route network; and • Roux’s prediction on when South Africa will hit its EV tipping point – and the two ingredients he says the market still needs: sub-R500 000 EVs and a genuinely reliable national charging network.

    TCS | The Cape Town start-up listening for TB with AI

    AI Diagnostics, a Cape Town-based med-tech company that has built an AI-powered stethoscope designed to detect tuberculosis, recently raised R85-million in a pre-series-A funding round. In this episode of the TechCentral Show (TCS), Nkosinathi Ndlovu speaks to the company’s CEO, Braden van Breda, about the funding round and its mission to transform TB screening across Africa and Asia. The round, led by the Steele Foundation for Hope, will fund the deployment of the Ostium – an AI-powered digital stethoscope that works in tandem with the company’s proprietary AI.TB model. The device is designed to detect signals associated with tuberculosis in lung sounds in real time, putting point-of-care diagnostic capabilities into the hands of the nurses, pharmacists and community health workers who often serve as the first contact in resource-constrained health systems. In a wide-ranging conversation, Van Breda explains why AI Diagnostics chose to tackle one of the world’s most underfunded diseases, and how an AI model can pick up TB signals that escape even trained clinicians. He also unpacks the painstaking work of building a TB-positive lung-sound dataset from scratch. Van Breda also delves into: • What the Ostium compares to a traditional stethoscope; • How the company handles real-world recording conditions, from noisy clinics to paediatric patients and HIV co-infection; • How AI Diagnostics stops the model from silently degrading as the device moves from a Khayelitsha clinic to rural Zambia or Vietnam; • The company’s goal of securing World Health Organisation certification and the path towards that; • How the Ostium is positioned against – or alongside – AI-assisted chest X-ray tools such as CAD4TB and Qure.ai's qXR; and • What it would realistically take to put an Ostium in every primary healthcare clinic on the continent by 2030.

    Werner Lindemann on how AI is rewriting the infosec rulebook

    The pace at which artificial intelligence is reshaping the threat landscape is outstripping the ability of most organisations to defend themselves, with shadow AI, synthetic identity attacks and a looming quantum computing disruption all converging at once. That’s the view of DataGroupIT CEO Werner Lindemann, who joined Duncan McLeod on the TechCentral Show to unpack what business leaders should be doing about AI and information security. Lindemann, who spent more than 30 years in senior roles at BCX and Clickatell before joining the security solutions distributor, says the African threat environment is no longer a watered-down version of what is happening elsewhere. Attackers are deploying the same AI-powered tools globally, and AI-enabled phishing campaigns now achieve click-through rates that traditional defences were never designed to withstand. A bigger blind spot, he argues, is shadow AI – employees pasting sensitive data into unapproved AI tools without oversight. Lindemann says this is fast eclipsing the shadow IT problem of the past decade because the tools are free, frictionless and often invisible to security teams. The conversation also tackles the credibility crisis facing identity verification. With AI now able to clone a CEO’s voice in real time or generate synthetic profiles that pass biometric checks, Lindemann believes traditional verification methods are fundamentally flawed. A big challenge is helping boards understand the issue in business rather than technical terms. Lindemann also weighs in on the rise of the chief AI officer role, following Sanlam’s recent appointment, and on whether African organisations are equipped to adopt AI at the pace global peers are setting given the continent’s acute skills shortage. The discussion closes on quantum computing. Lindemann challenges the conventional view that the quantum threat is a decade away, and outlines what business leaders should be doing now to prepare for the post-quantum cryptography world – even if the risk still feels distant.

    Donovan Marsh on AI and the future of filmmaking

    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 output quality. Marsh acknowledges the disruption this implies for camera operators, lighting crews, set designers and extras. But he argues that AI filmmaking could prove liberating for smaller filmmaking markets like South Africa, where the budgets to make ambitious local movies have dwindled. He has co-founded Dragon Studios AI with Ronnie Apteker and Stephen Cholerton, and is developing what he believes will be among the first AI-generated feature films. The tools are not quite there yet for a full 90-minute production, he says, but the gap is closing fast. Marsh also weighs in on where the so-called “uncanny valley” still trips up generative video, the future of the acting profession and what AI filmmaking could look like by 2029.
