Márcia Dantas abre o coração sobre os bastidores da televisão e o peso de ser mulher diante das câmeras. Depois de anos noticiando tragédias, ela própria virou notícia, não por um prêmio, mas por dizer em rede nacional que queria ser mãe. Poucos dias depois, foi demitida. Em sua fala, Márcia expõe como a maternidade ainda é tratada como risco, como o corpo feminino é constantemente julgado e como o mercado pune mulheres por escolhas legítimas. Sua história é um chamado para repensarmos o trabalho, a equidade e, sobretudo, a liberdade das mulheres de viverem suas vidas sem medo de serem silenciadas.

In this captivating and relatable TEDxUniversityofPretoria talk, Des invites us to view Artificial Intelligence as a modern kaleidoscope — one that reveals ever-changing patterns of opportunity, challenge, and transformation with each twist of innovation.Through personal reflection and academic research, Des explores how AI is reshaping education, work, and human potential — not as a distant future, but as a present reality. He uncovers a striking gap: while the world races to adopt AI, our institutions remain behind, preparing tomorrow’s leaders with yesterday’s tools.Drawing from his research in Public Administration and skills development, Des challenges us to rethink how we teach and prepare the next generation. He argues that AI must be integrated ethically and inclusively into our education systems — especially in non-STEM fields — so that the leaders of tomorrow can thrive in a world shaped by intelligent technology.Des’s message is one of empowerment, not fear: AI isn’t here to replace us; it’s here to amplify human creativity, curiosity, and capability. The real danger isn’t AI itself — it’s refusing to turn the kaleidoscope and see what’s possible.#TEDxUniversityofPretoria #ArtificialIntelligence #Education #FutureOfWork #Innovation #Leadership #Technology #AIinAfrica Des Kamukapa is a dynamic Research Consultant in the Skills and Enterprise Development environment; entrepreneur; public speaking coach; and business radio presenter.
