Arvind Krishna (IBM) and Nikesh Arora (Palo Alto Networks) discuss the quantum threat to current cryptography, with estimates that quantum computers could break today's encryption around 2030, and urge enterprises to adopt post-quantum security now. They also cover open vs. frontier AI model economics, AI-driven cyber offense and defense, geopolitics and regulation, and pressure on SaaS valuations. Their core conclusion is that organizations must act now on quantum-safe infrastructure and that open-weight models will take a large share of enterprise token usage.
- Krishna says DARPA's Quantum Benchmarking Initiative has narrowed from a couple hundred companies to about 13, and that a quantum computer capable of breaking today's cryptography could arrive around 2028-2033, with 2030 as a midpoint.
- Krishna notes that post-quantum cryptography is well understood and code exists, but organizations have been slow to adopt it, and that encrypted data stolen today could be decrypted later.
- Krishna predicts that someone will claim error correction on a running quantum computer by next year, with one or two players making real progress by 2027, and that gate-computation counts could scale from around 10,000 toward 10 million by 2029.
- Arora argues enterprises should replace IT stacks with quantum-safe infrastructure now, since the migration cannot be done quickly once the threat arrives, and stopgap post-quantum wrapping of traffic is available.
- Krishna argues that AI models cannot practically break quantum-level cryptography soon because quantum algorithms need quantum hardware to run efficiently, though a classical breakthrough in number theory remains possible.
- Arora says enterprises should use the best models during experimentation, then move most production tasks to small, task-specific or open-weight models for cost and auditability, reserving frontier models for high-value cases like breach response.
- Krishna estimates that 75% to 90% of token usage will shift to open-weight models due to cost (a roughly 40x difference), IP protection, and geopolitics, with the gap between Chinese and Western open models at 6 to 12 months.
- On cyber, both note that AI models like Mythos find vulnerabilities but hallucinate often, and Arora proposes pooling vulnerability discoveries among trusted parties so patches can be distributed to all customers.
