In the last year, a study found that more than half of all long-form LinkedIn posts were likely written by generative AI. What started as a platform for professional networking has quietly become an algorithmic echo chamber, and in 2025 where AI writes for AI, and originality is the rarest skill in the room.
From networking hub to synthetic feed
LinkedIn’s early promise was simple: connect professionals, share insights, and build credibility through expertise. But over the past two years, the feed has been flooded with AI-generated think pieces, perfectly structured, jargon-heavy, and devoid of lived experience. The result? A platform that sounds polished, but feels hollow.
The Study that changed the conversation
According to research by Originality AI, which analyzed 8,795 English-language posts over 100 words between 2018 and late 2024, 54% were likely AI-written. The spike began in 2023 with ChatGPT’s mass adoption, and while it has since leveled off, the baseline has shifted: AI authorship is now normal, not exceptional.
Why LinkedIn is the perfect AI habitat
Corporate speak has always been LinkedIn’s native language, safe, polite, and heavy with buzzwords. Generative AI is trained to excel at exactly that. The platform even offers built-in AI writing tools for premium users, turning the act of posting into a point-and-click exercise in producing “engagement-ready” copy.
The cost of losing human texture
For readers, the shift is subtle but corrosive. Posts feel interchangeable. Emotional nuance, hard-won insight, even small quirks of phrasing, all are smoothed away by the algorithm’s invisible hand. Without these imperfections, content loses the spark that makes it memorable and persuasive.
The danger for brands and thought Leaders
When everyone sounds the same, differentiation becomes impossible. AI-generated content might win short-term visibility, but it erodes long-term trust. Professionals who rely too heavily on AI risk being perceived as generic, the exact opposite of what LinkedIn was built to showcase.
