How AI Gets Smarter: Insights from Wits University Research
Quick summary
Wits University research sheds light on why artificial intelligence systems get smarter as they grow larger, offering insights into potential impacts on South African jobs, businesses, and consumers.
What happened
New research from the University of the Witwatersrand (Wits) in Johannesburg has made progress in understanding why artificial intelligence (AI) systems become smarter as they scale up. AI technology relies on complex networks that need enormous amounts of data and computational power, and this new study provides a fresh explanation for how AI performance improves with size.
AI models, such as those used in chatbots, online search, and voice assistants, have surprised researchers by becoming significantly better at tasks when their algorithms include more data and parameters. The Wits study dives deeper into this puzzle by looking at how information spreads and is processed inside these large AI models.
Why it matters
Understanding why AI gets smarter as it grows is important because AI is increasingly part of everyday life—whether through personalized ads, customer service bots, or tools to help businesses make decisions. This research adds to global efforts to explain why AI behaves the way it does and could lead to more efficient ways to develop smarter machines.
For South Africa, a country striving to boost technology adoption and digital transformation, this insight could support local AI innovation and help South African tech companies use AI more effectively. It also opens up conversations about preparing workplaces and the economy for AI’s expanding role.
What this means for South Africans
As AI technology scales and improves, it will influence many aspects of daily life in South Africa. For consumers, smarter AI can provide more tailored online experiences, from better recommendations for shopping and entertainment to improved virtual assistants offering support in multiple South African languages.
For students and job seekers, understanding AI’s growth means being aware of the skills needed in the future job market. AI can automate repetitive tasks but also creates opportunities in AI development, data science, and AI ethics. South Africans entering the workforce can benefit from gaining AI-related skills to stay competitive.
Impact on consumers, jobs and small businesses
Smarter AI offers benefits for small businesses by helping them compete more effectively. For example, AI-powered marketing tools can analyze customer patterns and create affordable, personalised advertising campaigns. Small retailers or service providers could use AI chatbots to handle simple customer queries, freeing up time and resources.
However, there are concerns about AI replacing certain types of jobs, especially in administrative or routine roles. South Africa’s high unemployment rate makes it critical to balance AI adoption with job creation strategies that focus on reskilling and creating new roles that AI can support but not replace.
Consumers might also face challenges such as privacy concerns and overreliance on automated systems. The government and private sector need to ensure that AI’s growth is inclusive and transparent so that it doesn’t widen existing inequalities.
Risks and limitations
While AI gets smarter as it scales, there are important caveats. Large AI models require vast computing power, which can be expensive and environmentally taxing—a significant consideration for South Africa’s energy supply and climate goals.
Moreover, smarter AI doesn’t always mean error-free or unbiased. AI systems can still reflect the biases in their training data or make unpredictable mistakes. Without proper oversight, reliance on AI could lead to unfair decisions, especially in sensitive areas like credit scoring or hiring.
South Africans need to be cautious and informed users of AI technology, pushing for regulations that protect consumers and promote ethical use.
The Wits University study is a valuable step forward in unraveling AI’s mysteries. It highlights the importance of scientific research in making sure AI grows smarter in ways that benefit society as a whole, including South Africa’s unique social and economic landscape.
OnABudget takeaway
AI’s ability to learn better as it grows means we’ll see smarter tools that can help with everyday tasks and business challenges. For South Africans, this calls for staying informed, gaining new skills, and supporting policies that encourage fair and responsible AI use.
