Ray Kurzweil Doubts Quantum Computing Will Crack Crypto

Futurist and ex-Google engineer Ray Kurzweil expressed skepticism about quantum computing's potential to break modern cryptography, pointing to a decade of unfulfilled promises and persistent high error rates.

Ray Kurzweil, a well-known futurist and former Google engineer, has cast doubt on the prospects of quantum computing. In a recent statement, he noted that the industry has been promising a breakthrough capable of cracking modern cryptography for over ten years, yet practical systems remain plagued by high error rates and fail to deliver real-world results.

"So I'm not sure about quantum computing. I don't think it will work, although it is fascinating and very interesting," Kurzweil said. He also argued that advances in artificial intelligence do not depend on the success of quantum computers. Existing technologies, he believes, are sufficient to move toward artificial general intelligence (AGI), and further progress in AI will be driven by classical computing systems without the need for quantum acceleration.

The remarks come amid ongoing debates about the potential threat quantum computing poses to cryptographic standards underlying cryptocurrencies like Bitcoin. Kurzweil's skepticism suggests that such risks remain distant.
