I took six weeks off to raise a baby and everyone decided it was the time to declare the AI revolution imminent. It's hard not to take it personally. The tick-tock of new developments, each more impressive than the last – and each arriving on the scene faster than the last – hit its apogee last week with the near-simultaneous announcement of Google's Bard and Microsoft's Bing Chat. Since then, there's been possible permutation of the discourse, from millenarian claims of an imminent AI eschaton to rejection of the entire field as glorified autocomplete. I'm not here to settle that debate.

NASA's mission of exploration requires leveraging new ways to utilize and learn from the unprecedented amount of data that space-based observation platforms generate. New capabilities are needed, ranging from onboard autonomy for robotic spacecraft to techniques for understanding the world and universe where we live. Artificial Intelligence (AI) and data science are rapidly becoming integral to NASA's future to drive automation and interpretation. AI is a collection of advanced technologies that allow machines to think and act, through sensing, comprehending, interacting, and learning. AI's foundations lie at the intersection of several traditional fields - Philosophy, Mathematics, Economics, Neuroscience, Psychology, and Computer Science.

Microsoft will work with organisations in the UK to develop artificial intelligence that helps the planet and people with disabilities, the company has announced at Future Decoded. Lucas Joppa, Microsoft's Chief Environmental Officer, used his keynote speech at the London event to launch the second AI for Good programme and invited ventures to apply. The four-month accelerator will have space for 12 start-ups, charities, social enterprises and small and medium-sized businesses that have a social mission. It will give them credits for Azure, Microsoft's cloud platform, a curriculum designed by Microsoft Startups, Social Tech Trust and Microsoft, access to workshops that will help develop their products and bring them to the market, and contact with relevant speakers. "AI is one of the most important tools we have to accelerate innovation at the speed and scale we need to address climate change and other important societal challenges," Joppa said.
