BlackBerry may be best known for its QWERTY-keyboard smartphones, but the company today is building its next chapter around software for cars, robots and secure communications.

BlackBerry CEO John Giamatteo joins CNBC’s Arjun Kharpal to explain how the company has reinvented itself around QNX, BlackBerry’s operating system used in software-defined vehicles.

He discusses why BlackBerry sees physical AI as a major growth opportunity, from autonomous vehicles and warehouse robots to surgical systems and industrial automation. As more machines become connected, Giamatteo argues that safety-certified software will become increasingly important.

The conversation also covers how AI is changing the cybersecurity threat landscape, why Giamatteo sees governments’ use of consumer messaging apps as a security risk, and how BlackBerry is adapting its encryption technology as threats from AI and quantum computing evolve.

Europe has no shortage of technology ideas or startups. Its challenge is turning them into global companies — and keeping more of its most successful businesses in Europe.

Arm co-founder Hermann Hauser, who also co-founded Amadeus Capital, joins CNBC’s Arjun Kharpal to explain why Europe struggles to scale its technology companies. He discusses the need for growth capital and experienced management to help European companies scale, as well as access to critical technologies if Europe is to avoid becoming what he calls a U.S. “technology colony.”

The conversation also covers AI and quantum computing. Hauser explains why some AI valuations have moved ahead of the fundamentals, where AI’s long-term value could be created and why quantum’s encryption-breaking “Q Day” could arrive as early as 2029.

Hauser also examines new chip architectures designed to reduce AI’s energy demands and recounts Arm’s early history and its relationship with Apple.
