Experts debate when quantum computers could break modern encryption

Scientists are divided over when quantum computers will become powerful enough to break today’s digital encryption, a moment widely referred to as ‘Q–Day’.

While predictions range from just two years to several decades, experts agree that governments and companies must begin preparing urgently for a future where conventional security systems may fail.

Quantum computing uses subatomic behaviour to process data far faster than classical machines, enabling rapid decryption of information once considered secure.

Financial systems, healthcare data, government communications, and military networks could all become vulnerable as advanced quantum machines emerge.

Major technology firms have already made breakthroughs, accelerating concerns that encryption safeguards could be overwhelmed sooner than expected.

Several cybersecurity specialists warn that sensitive data is already being harvested and stored for future decryption, a strategy known as ‘harvest now, decrypt later’.

Regulators in the UK and the US have set timelines for shifting to post-quantum cryptography, aiming for full migration by 2030-2035. However, engineering challenges and unresolved technical barriers continue to cast uncertainty over the pace of progress.

Despite scepticism over timelines, experts agree that early preparation remains the safest approach. Experts stress that education, infrastructure upgrades, and global cooperation are vital to prevent disruption as quantum technology advances.

AI project seeks major leap in diabetes care

A major research initiative led by the University of Virginia has secured $4.7 million to advance machine learning in Type 1 diabetes care.

The project, backed by Breakthrough T1D and the Helmsley Charitable Trust, aims to develop fully automated insulin systems that adapt continuously to patient needs.

The research will combine adaptive algorithms with ultra-rapid insulin to enable personalised glucose control without manual input. The University of Virginia will lead engineering and algorithm development, with clinical trials conducted across multiple US research centres.

At its core is an AI framework that learns from real-time data, adapting to metabolic changes, stress, and daily rhythms. Researchers aim to overcome the limitations of current automated insulin systems, which still rely on fixed parameters and regular user intervention.

The collaboration reflects a shift towards patient-centred AI, aiming to reduce daily diabetes management burdens while improving safety and quality of life. Developers say the technology could offer families greater freedom and long-term stability in managing chronic conditions.

TikTok struggles to stabilise US infrastructure after data centre outage

TikTok says recovery of its US infrastructure is progressing, although technical issues continue to affect parts of the platform after a data centre power outage.

The disruption followed the launch of a new US-based entity backed by American investors, a move aimed at avoiding a nationwide ban.

Users across the country reported problems with searches, video playback, posting content, loading comments and unexpected behaviour in the For You algorithm. TikTok said the outage also affected other apps and warned that slower load times and timeouts may persist, rather than returning to normal performance.

In a statement posted by the TikTok USDS Joint Venture, the company said collaboration with its US data centre partner has restored much of the infrastructure, but posting new content may still trigger errors.

Creators may also see missing views, likes, or earnings due to server timeouts rather than actual data loss.

TikTok has not named the data centre partner involved, while severe winter storms across the US may have contributed to the outage. Despite growing scepticism around the timing of the disruption, the company insists that user data and engagement remain secure.

OpenAI prepares ad rollout inside free ChatGPT service

Advertising is set to be introduced within the free ChatGPT service, signalling a shift in how the platform will be monetised as its user base continues to expand rapidly. The move reflects OpenAI’s plans to turn widespread adoption into a sustainable revenue stream.

The company confirmed that ad testing will begin in the coming weeks, with sponsored content shown at the bottom of relevant ChatGPT responses. OpenAI said advertisements will be clearly labelled and separated from organic answers.

ChatGPT now serves more than 800 million users globally, most of whom currently access the service at no cost. Despite the high valuation, the company has continued to operate at a loss while expanding its infrastructure and AI capabilities.

Advertising represents OpenAI’s latest effort to diversify income beyond paid subscriptions and enterprise services. Sponsored recommendations will be shown only when products or services are deemed relevant to the user’s ongoing conversation.

The shift places OpenAI closer to traditional digital platform business models, raising broader questions about how commercial incentives may shape conversational AI systems as they become central gateways to online information.

Facial recognition and AI power Android’s new theft protection upgrades

Android is rolling out expanded theft protection features aimed at reducing financial fraud and safeguarding personal data when smartphones are stolen, with new security controls now available across recent device versions.

The latest updates introduce stronger protections against unauthorised access, including tighter lockout rules after failed authentication attempts and broader biometric safeguards covering third-party apps such as banking services and password managers.

Recovery tools are also being enhanced, with remote locking now offering optional security challenges to ensure only verified owners can secure lost or stolen devices through web access.

For new Android devices activated in Brazil, AI-powered theft detection and remote locking are enabled by default, using on-device intelligence to identify snatch-and-run incidents and immediately lock the screen.

The expanded protections reflect a broader shift towards multi-layered mobile security, as device makers respond to rising phone theft linked to identity fraud, financial crime, and data exploitation.

India considers social media bans for children under 16

India is emerging as a potential test case for age-based social media restrictions as several states examine Australia-style bans on children’s access to platforms.

Goa and Andhra Pradesh are studying whether to prohibit social media use for those under 16, citing growing concerns over online safety and youth well-being. The debate has also reached the judiciary, with the Madras High Court urging the federal government to consider similar measures.

The proposals carry major implications for global technology companies, given that India’s internet population exceeds one billion users and continues to skew young.

Platforms such as Meta, Google and X rely heavily on India for long-term growth, advertising revenue and user expansion. Industry voices argue parental oversight is more effective than government bans, warning that restrictions could push minors towards unregulated digital spaces.

Australia’s under-16 ban, which entered force in late 2025, has already exposed enforcement difficulties, particularly around age verification and privacy risks. Determining users’ ages accurately remains challenging, while digital identity systems raise concerns about data security and surveillance.

Legal experts note that internet governance falls under India’s federal authority, limiting what individual states can enforce without central approval.

Although the data protection law of India includes safeguards for children, full implementation will extend through 2027, leaving policymakers to balance child protection, platform accountability and unintended consequences.

Austrian watchdog rules against Microsoft education tracking

Microsoft has been found to have unlawfully placed tracking cookies on a child’s device without valid consent, following a ruling by Austria’s data protection authority.

The case stems from a complaint filed by a privacy group, noyb, concerning Microsoft 365 Education, a platform used by millions of pupils and teachers across Europe.

According to the decision, Microsoft deployed cookies that analysed user behaviour, collected browser data and served advertising purposes, despite being used in an educational context involving minors. The Austrian authority ordered the company to cease the unlawful tracking within four weeks.

Noyb warned the ruling could have broader implications for organisations relying on Microsoft software, particularly schools and public bodies. A data protection lawyer at the group criticised Microsoft’s approach to privacy, arguing that protections appear secondary to marketing considerations.

The ruling follows earlier GDPR findings against Microsoft, including violations of access rights and concerns raised over the European Commission’s own use of Microsoft 365.

Although previous enforcement actions were closed after contractual changes, regulatory scrutiny of Microsoft’s education and public sector products continues.

Anthropic CEO warns of civilisation-level AI risk

Anthropic chief executive Dario Amodei has issued a stark warning that superhuman AI could inflict civilisation-level damage unless governments and industry act far more quickly and seriously.

In a forthcoming essay, Amodei argues humanity is approaching a critical transition that will test whether political, social and technological systems are mature enough to handle unprecedented power.

Amodei believes AI systems will soon outperform humans across nearly every field, describing a future ‘country of geniuses in a data centre’ capable of autonomous and continuous creation.

He warns that such systems could rival nation-states in influence, accelerating economic disruption while placing extraordinary power in the hands of a small number of actors.

Among the gravest dangers, Amodei highlights mass displacement of white-collar jobs, rising biological security risks and the empowerment of authoritarian governments through advanced surveillance and control.

He also cautions that AI companies themselves pose systemic risks due to their control over frontier models, infrastructure and user attention at a global scale.

Despite the severity of his concerns, Amodei maintains cautious optimism, arguing that meaningful governance, transparency and public engagement could still steer AI development towards beneficial outcomes.

Without urgent action, however, he warns that financial incentives and political complacency may override restraint during the most consequential technological shift humanity has faced.
