Remember BlackBerry? Yes, that BlackBerry: The phone with a physical keyboard that everyone used and suddenly became obsolete after Apple introduced the iPhone.

Well, it’s making a comeback.

The new BlackBerry isn’t a mobile device, but it’s a “mission-critical software layer in the physical AI stack,” and the stock is surging.

BlackBerry hasn’t made a consumer mobile device in years. Instead, it has quietly transformed into a high-tech powerhouse focused entirely on the world of “Physical AI” and robotics.

The secret weapon? The rock-solid software framework called QNX that acts as the “uncrashable” nervous system for autonomous machines. That means BlackBerry’s software is being used by massive chipmakers such as Nvidia and AMD to build smart cars and warehouse robots. The software makes sure those machines move safely with zero lag.

“As intelligent machines become increasingly autonomous and operate around people, the requirements for safety, security, reliability and real-time determinism become even more important,” CEO John Giamatteo said during an earnings call. “Unlike probabilistic AI systems, QNX technology is deterministic and safety certified, which is exactly why it is so hard to replicate and why customers trust it for systems where failure is not an option.”
