Tech News Digest: Monday, 13 April 2026

Monday's digest opens a new week with significant news from the World Economic Forum's AI report, a major UK retail AI deployment, and the latest chapter in the ongoing battle for AI search market share. Plus: why this might be the most important skill a UK professional can develop right now.

WEF AI Report: UK in Top 5 for AI Readiness Globally

The World Economic Forum's annual Global AI Readiness Index placed the UK fifth globally, behind the US, Singapore, South Korea, and Canada — an improvement of two positions from last year. The UK scores particularly strongly on AI research output, regulatory framework clarity, and digital infrastructure. Areas identified for improvement include AI skills across the broader workforce (outside the tech sector), regional disparity in AI adoption between London and other parts of the UK, and the pace of AI adoption in the public sector relative to comparable nations. The report's authors note that the UK's performance is all the more impressive given its post-Brexit adjustment period, which temporarily complicated European research collaboration. The government has cited the ranking as evidence that its approach — supportive and principles-based rather than prescriptive — is delivering results.

Marks & Spencer Deploys AI-Powered Demand Forecasting Across 1,000 Stores

Marks & Spencer completed the rollout of an AI-powered demand forecasting and stock replenishment system across all 1,000 of its UK stores, following a 12-month phased deployment. The system uses real-time sales data, weather forecasts, local events, and seasonal patterns to predict demand at SKU level and automatically generate replenishment orders, reducing both overstock waste and out-of-stock incidents. Early results from the pilot stores showed a 23% reduction in food waste and a 12% improvement in product availability. M&S Food, where availability and freshness are particularly critical to the customer proposition, is reported to be the biggest beneficiary. The deployment was built on a Microsoft Azure AI foundation and represents one of the largest retail AI implementations in the UK to date. M&S says the system has paid back its implementation cost in under 18 months.

Perplexity vs. Google: AI Search Market Share Battle Intensifies

New data from web analytics firm Similarweb shows Perplexity AI now accounts for 8% of AI-assisted search queries in the UK — up from 2% a year ago — while Google's AI Overviews handles the vast majority of the remainder. The growth reflects increasing user preference for Perplexity's citation-heavy, conversational format for research tasks, while Google retains dominance for quick lookups and navigational queries. Microsoft Bing's Copilot holds approximately 12% of the AI search market in the UK, with DuckDuckGo AI rounding out the field. For content publishers, the fragmentation creates new challenges: optimising for AI-assisted search requires different strategies than traditional SEO, and being cited as a source in Perplexity answers may become as valuable as a first-page Google ranking for specialist topics. SEO professionals in the UK are actively developing "answer engine optimisation" strategies to capture AI search visibility.

The Most Important Skill UK Professionals Can Develop Right Now

If you could develop only one professional skill in 2026, what should it be? The answer that keeps emerging from research into high-performing UK workers, successful freelancers, and fast-growing startups is the same: the ability to think clearly about what AI can and can't do in your specific context, and to design workflows that combine AI efficiency with human judgment effectively. This isn't "learn to code" or even "learn prompt engineering" — it's a meta-skill about augmenting your thinking with AI tools strategically. The highest-value version of this skill shows up as: knowing when to trust AI output and when to verify it; understanding how to break a complex task into AI-delegatable and human-required components; and staying current with new tools without chasing every shiny thing. It's learnable through deliberate practice. Start with your most time-consuming workflow and ask: what part of this could AI handle, and what part requires me?

UK Smart Home Market Reaches £4bn as AI Devices Drive Growth

The UK smart home market reached £4 billion in annual revenue in 2025, according to new figures from Statista, with AI-enabled devices (smart speakers, AI thermostats, intelligent security cameras, and voice-controlled appliances) accounting for 62% of sales — up from 45% three years ago. Amazon Echo, Google Nest, and Apple HomePod remain the dominant smart speaker platforms, but a new wave of AI-native devices from specialist startups is growing rapidly. UK consumers show a particular preference for energy management smart home technology, driven by high electricity prices and growing environmental awareness. The energy-saving potential of AI-managed heating and appliance scheduling has been quantified by the Energy Saving Trust at an average of £340/year for a fully smart-enabled home — a meaningful ROI on device investment. Penetration is highest in London and the South East but growing strongly in the Midlands and North.
