Perplexity CEO: AI Success Depends On Energy Efficiency

Perplexity CEO Aravind Srinivas said AI companies that generate the most economic value from the least amount of computing power will be best positioned to succeed as competition intensifies across the sector. Speaking to CNBC’s Elaine Yu, Srinivas argued that maximizing “token value per watt per user” will become a key metric for evaluating AI businesses.

Balancing Accuracy, Latency, Cost And Privacy

Srinivas explained that every AI token, the basic unit of data processed by a model, consumes energy. Companies that can optimize the relationship between energy use and economic output, he said, will have a significant advantage. “Whoever is able to maximize this particular objective by balancing accuracy, latency, cost, privacy and intelligence really will win in the long term,” Srinivas said. His comments reflect a growing focus within the AI industry on efficiency as companies face rising infrastructure and computing costs.

Advancing Agentic AI With A Platform-Agnostic Approach

Perplexity continues to expand its work in agentic AI, systems designed to complete complex tasks rather than respond to individual prompts. In February, the company introduced Perplexity Computer, an AI agent capable of handling multi-step tasks over extended periods. While Perplexity develops its own models, its products also incorporate technology from companies including Anthropic.

The company recently launched Personal Computer, an orchestration layer that routes queries to the most appropriate processing resource. Srinivas described the shift as a move toward bringing more AI capabilities directly onto personal devices rather than relying exclusively on centralized data centres. According to Srinivas, this approach can reduce energy consumption while improving privacy and security.

Integration Across Leading Platforms And Growing Competition

Personal Computer is currently available on Apple’s Mac devices and is expected to expand to Microsoft’s Windows platform. The system is designed to work across applications, including Word and Outlook. The strategy also differentiates Perplexity from competitors such as OpenAI, Anthropic and Google, which are building increasingly integrated AI ecosystems around their own models and platforms.

Despite rapid growth among rivals, Srinivas said Perplexity’s focus remains on creating a system that works across different models, chips and operating systems. “We believe we’re building the most versatile operating system by making it work across different models, chips, and operating systems,” he said.

Future Outlook: Sustainable And Enduring Advantage

Perplexity’s approach allows the company to incorporate advances from multiple AI providers rather than relying on a single model ecosystem. The strategy has coincided with strong business growth. According to Srinivas, the company’s annualized revenue has tripled since the beginning of the year. As competition intensifies across the AI sector, efficiency, infrastructure costs and cross-platform integration are becoming increasingly important factors for companies seeking to scale their products and services.

Europe’s Deadly Summer Heat Exposed The Cost Of A Warming Continent

by THEFUTURE.TEAM

October 23, 2026

Europe experienced its deadliest summer for heat-related deaths on record in 2026, with an estimated 24,400 excess deaths linked to extreme temperatures across 30 countries. Researchers estimate that human-induced climate change was responsible for around 32,000 of the deaths attributed to heat in the study’s broader analysis, accounting for 65% of the total.

The findings highlight the growing public-health consequences of global warming, largely driven by fossil fuel use, as extreme heat becomes more frequent and severe.

A Summer Of Dangerous Heat

Between June and August, heatwaves pushed temperatures in Western Europe to an average of 2.9°C above the 1991–2020 norm, with some days reaching 12°C above average. Nearly a third of estimated heat-related deaths occurred during a particularly intense heatwave between 17 June and 1 July.

“These numbers are a stark reminder that our hotter, more extreme summers are having an increasingly severe impact on public health,” said Dr Clair Barnes, a researcher at Imperial College London and co-author of the study.

The estimated toll exceeded previous peaks of around 29,000 deaths in summer 2022 and 28,000 in 2003 across the region studied.

How Researchers Estimated The Toll

Researchers modelled the relationship between temperature and mortality across 854 urban areas in the EU, UK, Norway and Switzerland, covering around 40% of the population in the 30 countries studied.

The analysis incorporated temperature records, age, socioeconomic conditions, environmental factors and access to healthcare. By comparing actual temperatures with those expected without human-induced warming, the team estimated the additional deaths attributable to climate change.

Final official mortality figures for summer 2026 are not yet available in many countries, and heat-related deaths are often underreported because their effects can be difficult to identify directly.

Older People Face The Greatest Risk

People aged 85 and over accounted for roughly half of the estimated deaths. However, the impact extended across age groups, with around 800 excess deaths among adults aged 20–44 and approximately 6,000 among people under 65.

Southern Europe experienced the highest mortality burden, reflecting hotter temperatures and other vulnerabilities, including air pollution, limited green space and unequal access to healthcare and heat-alert systems.

Italy, France And Spain Record Highest Toll

Italy recorded an estimated 13,303 heat-related excess deaths, followed by France with 7,268 and Spain with 6,824. Germany recorded around 6,340, while the UK saw an estimated 4,354 deaths.

In the UK, the heat also placed significant pressure on healthcare services. Andrew Hartle, Professor of Practice of Anaesthesia at Imperial College Healthcare, said demand during the summer resembled that of a severe winter virus season.

Cities Urged To Strengthen Heat Protection

Researchers say cities can reduce the risks through climate shelters, external shading and building retrofits, alongside measures to help residents avoid exposure during the hottest hours. Checking on vulnerable people, staying hydrated and following heat alerts are also important.

The researchers stress that adaptation must go hand in hand with reducing fossil fuel use to limit further warming. The findings underline that extreme heat is already a major public-health threat across Europe, with thousands of lives at risk each summer.
