Pangram posted data on how much AI is being used on social media. Chances are that any long-form post on LinkedIn had at least some AI help.
This quote gave me a chuckle (emphasis mine).
"LinkedIn also encourages AI use on its platform in several ways, including a built-in "Write with AI" button (now rebranded "Enhance post," but still offering AI writing assistance). People are noticing LinkedIn's growing reputation for slop – perhaps to combat it, an executive at LinkedIn recently announced that the platform would be detecting and downranking AI-generated posts using an in-house algorithm; ironically, the announcement was itself AI-generated. Whether or not the company is attempting to modulate AI in their feed, our users are still seeing a lot of AI writing on LinkedIn."
