ARM: Most powerful chip company you barely notice is shaping AI future

The article highlights ARM as a quietly dominant force in modern computing, whose processor designs underpin a vast array of devices—from smartphones and laptops to autonomous vehicles and smart home appliances. Unlike traditional chip manufacturers, ARM does not produce physical chips but instead licenses its processor architectures to other companies. This business model has allowed ARM to become central to the industry, especially as energy efficiency becomes as critical as raw performance in emerging fields like AI, robotics, and autonomous driving. ARM’s architecture has shaped software ecosystems over decades, creating a feedback loop where widespread device adoption drives developer engagement, further cementing ARM’s influence. At a technical level, the article explains that processors, particularly CPUs, function as massive collections of electronic switches (transistors) that operate using binary logic to execute instructions and perform calculations. ARM’s designs focus on efficient, low-power computing, which aligns well with the needs of mobile and embedded devices. The article also touches on the evolution of computing from mechanical calculators to modern silicon-based processors, emphasizing the fundamental
