Computer scientist Sasha Luccioni is a pioneering voice in AI, especially when it comes to its environmental impact. We speak to her as she is announced on the BBC 100 Women list. We also meet one of the only AI startups in Bhutan, and the two friends who met online and have finally met in real life – after 13 years of knowing each other.
