AI Agents Everywhere (2026)
In 2026, AI agents are no longer an experiment but an everyday reality. Claude Code manages codebases autonomously. Intercom Fin resolves 50%+ of customer queries without human intervention. Microsoft 365 Copilot drafts emails, summarizes meetings and analyzes data automatically. Companies that have not yet deployed AI agents are significantly lagging behind in productivity.
Integration in All Software
In 2026, virtually all professional software includes AI features: accounting software that categorizes automatically, legal tools that analyze contracts, medical software that supports diagnoses, and HR systems that screen CVs. AI has become infrastructure, no longer just a feature.
