What is sovereignty in AI?
What does it mean for artificial intelligence to be sovereign? This week, Technology Now explores how more than just data can be sovereign, our AI models using the data can be too. We ask what it actually means for AI models to be sovereign and why companies, and indeed entire countries, would be interested in this concept. Andreas Geiss, Vice-President Automotive & Manufacturing at Aleph Alpha tells us more. This is Technology Now, a weekly show from Hewlett Packard Enterprise.

How can you balance AI and sustainability?
How intertwined are AI and sustainability? This week, Technology now explores how we can do more than just use AI in a more sustainable and ethical way, we can harness it as a powerful tool to contribute to sustainability in other industries too. We ask which challenges are facing AI when it comes to sustainability and how can companies build strategies that support more efficient IT. Monica Batchelder, Chief Sustainability Officer at HPE, tells us more.This is Technology Now, a weekly show from Hewlett Packard Enterprise.
