New research on breaking elliptic-curve signatures with far fewer qubits than previously estimated has prompted Google and Cloudflare to target full post-quantum readiness by 2029, several years ahead of Microsoft, Amazon and lagging peers. The probability of a cryptographically relevant quantum computer arriving before 2035 remains low but the downside is existential, shifting priority from stored-data attacks to real-time authentication threats. Prudent risk management requires coordinated acceleration across the entire technology stack; waiting for certainty guarantees failure.
What outlets missed
Coverage largely treated company timelines and qubit estimates in isolation. Few noted that Google's circuits still require 70-90 million Toffoli gates, an operation currently difficult to scale. Current quantum hardware realities received little attention: the largest experimental arrays sit at roughly 6,000 qubits while fault-tolerant systems may need hundreds of thousands of physical qubits for error correction. The IOWN Forum's optical interconnect work was not linked to the classical control layer quantum computers will need. Technology Review's maintenance critique never addressed cryptographic upkeep as a civilizational-scale maintenance problem. No outlet fully reconciled the tension between rapid innovation in quantum research and the slow, unglamorous work of updating billions of devices and certificates.
As Big Tech Pursues AI Dominance Experts Warn of Neglected Maintenance
Stewart Brand has built a career spotting where culture and technology collide, from the Whole Earth Catalog to his influence on early cyberculture. His latest project, the handsome new volume Maintenance: Of Everything, Part One, attempts to reframe one of the least glamorous aspects of technological life as something radical. Brand argues that taking responsibility for keeping tools, systems, and even the planet itself in working order is not mere drudgery but a profound civic act. The book, the first in a planned series, aims to catalog the civilizational importance of maintenance and ultimately honor the people who perform it.
That message lands at a moment when the technology industry’s priorities look increasingly misaligned with reality. For more than a decade, academics have documented how innovation receives prestige, funding, and breathless media coverage while the work of oiling, patching, updating, and repairing is pushed to the margins. Lee Vinsel, a historian of technology and cofounder of the Maintainers, a global network studying repair, care, and upkeep, has watched this imbalance produce predictable results: creaking infrastructure, planned obsolescence, and corporate policies that treat repair as a threat to quarterly earnings rather than a public good. The right-to-repair movement has repeatedly exposed how manufacturers design products to be difficult or illegal to fix, locking owners out of their own devices in the name of profit. American infrastructure offers a daily reminder of what happens when maintenance is chronically deprioritized.
Now the stakes are rising. The same week Brand’s book drew attention, the IOWN Global Forum wrapped its annual meeting in Sydney and signaled that datacenter interconnects will be a primary focus for its all-optical networking technology. Backed by companies hoping to replace electrical connections with light all the way down to the chip level, IOWN has already demonstrated synchronous data replication across hundreds of kilometers of fiber with remarkably low latency. Steering committee chair Gonzalo Camarillo and use-case working group lead Katsutoshi Itoh told reporters that financial services firms in London see clear value in the approach. They want to shift AI and high-performance computing workloads to cheaper facilities outside expensive urban centers, but only if latency does not degrade performance.
IOWN’s backers believe the technology can give smaller operators and so-called neoclouds, which rent out GPUs, a fighting chance against hyperscalers that can afford to build everything in-house. In theory this scatters AI infrastructure more widely and reduces concentration risk. In practice it depends on the unglamorous work of maintaining an all-photonic network at scale, keeping fiber pristine, monitoring signal integrity, and updating protocols. The very need for such a project underscores how current infrastructure is already groaning under the weight of AI’s insatiable appetite for compute and power.
At the same time, the cryptography community is confronting its own maintenance crisis with far more immediate consequences. Recent advances in quantum computing have brought the industry uncomfortably close to “Q-Day,” the moment when large enough quantum machines can crack the public-key encryption protecting everything from banking transactions to state secrets. Ars Technica’s reporting on the uneven pace of post-quantum cryptography adoption paints a troubling picture. Some technology giants are accelerating their migration to quantum-resistant algorithms. Others continue with business as usual, even though the warning signs have existed for years.
The Flame malware operation, jointly developed by the United States and Israel around 2010, remains a chilling case study. Flame hijacked Microsoft’s own update mechanism by exploiting the long-known collision weaknesses in the MD5 hash function. The attackers minted a forged digital certificate that looked legitimate, then used it to push malicious code inside Iranian government networks. The vulnerability had been public since 2004. Research published in 2008 and 2009 proved its practical exploitability. Yet a slice of Microsoft’s infrastructure still relied on it. The incident did not bring down the global internet, but it proved that neglected maintenance of cryptographic standards can hand adversaries perfect weapons.
The parallel across these developments is hard to ignore. Whether the task is keeping legacy code secure, ensuring optical networks remain reliable over long distances, or simply designing consumer devices that last longer than a single product cycle, maintenance is treated as someone else’s problem until crisis strikes. Brand is correct that maintainers deserve honor, yet the economic incentives run in the opposite direction. Executives chase valuation multiples built on disruption narratives. Shareholders reward rapid growth over resilient systems. The people who patch, monitor, and repair rarely appear in glossy keynote presentations.
This imbalance carries democratic implications. When encryption standards fail, ordinary people, hospitals, schools, and small businesses pay the price while the largest technology firms hire teams of cryptographers to retrofit their own systems. When repair is deliberately complicated, consumers are forced into a cycle of replacement that feeds environmental harm and concentrates market power. When AI infrastructure clusters in a handful of locations because only a few players can afford the interconnects, the economic benefits of artificial intelligence flow to the usual coastal zip codes and established giants.
Brand’s call to treat maintenance as a radical act feels especially urgent now. The planet itself is the largest system we must maintain, and its climate, biodiversity, and resource limits will not be innovated away. The same habits of neglect that produced brittle software and unfixable gadgets have contributed to policy failures on energy grids, broadband access, and environmental monitoring. Scholars associated with the Maintainers have spent years showing that care work, whether performed by mechanics, systems administrators, or climate scientists, underpins every celebrated breakthrough.
If the technology industry truly wants to build an AI-powered future that is secure, distributed, and sustainable, it will need more than flashy optical networks or last-minute cryptographic patches. It will require a cultural and economic shift that values the people who keep systems alive long after the launch parties end. Brand’s book is only Part One. The coming volumes, and the real-world decisions made by executives and policymakers in the next few years, will determine whether we finally start fixing everything or continue breaking things faster than they can be repaired.
