In this article, we break down the most important AI applications gaining traction across the economy today, focusing on where real adoption and innovation are converging.
AI in Software Development
In tech companies, AI now contributes meaningful portions of production code. At Uber, AI has gone from writing under 1% of coding changes to over 8%.
Multimodal AI
AI systems are becoming fully multimodal across formats, being used for video generation, design, and industrial simulation. AI is evolving into a universal interface for all data types.
Enterprise Workflow Automation
AI is being embedded into HR, finance, and IT service desks, becoming a core infrastructure for corporations.
AI in Commerce
AI agents are now shopping online for users. In July 2025, traffic to U.S. retail sites from AI agents increased 4700% year-over-year, with 38% of consumers using AI for shopping.
Medical AI
AI is widely used to detect diseases from radiology scans and medical images. Over 1,200 AI medical devices have been FDA-cleared, with widespread adoption across health systems.
Legal AI
Use of AI is also rapidly spreading throughout the legal industry. AI tools allow lawyers to rapidly analyze case law, statutes, and precedents to support their legal strategy. 60% of lawyers say AI is already essential, and 95% expect it to be a central part of their workflow within 5 years.
