Digital marketing in 2016 vs 2026 - what changed

Hey guys, I wanted to understand how digital marketing has changed from 2016 to 2026. In 2016, it was mostly about Facebook organic reach, basic SEO, simple Google Ads, and email blasts. But in 2026, it feels more AI-driven, data-focused, automation-heavy, and dominated by short-form video and performance marketing. Everything is more competitive and personalized now. What do you think is the biggest change, and how should we prepare for the future?
