AI 营销泛滥，却没人再看：Pangram 扫描百万帖子发现 LinkedIn 超 40% 长文由 AI 撰写
Everyone Is Marketing with AI, and Nobody Is Listening
Pangram 扫描 100 万条帖子发现，LinkedIn 上超过 40% 的长帖完全由 AI 撰写，评论中 AI 占比甚至更高。UC Berkeley 研究者对一家约 200 人美国科技公司进行八个月研究，发现员工用 AI 提速后并未减少工时，反而承担更多任务、工作更久。AI 让营销和建站变得同样廉价，收件人和读者却已无暇顾及。

Everyone uses AI to market their stuff now. It writes the cold emails, the LinkedIn posts and the ads. It even writes the comments under other people's posts. But nobody is listening anymore. There is far more of it than anyone can read. And the people it is meant for are busy with their own AI projects.
I recently wrote about a developer who builds a booking app for hair salons over a weekend. Marketing the app with AI is now as easy as building it. An AI agent finds 2,000 salons and writes each owner an email that mentions their salon by name. It also posts on Instagram and LinkedIn each day. Setting it up takes an afternoon.
The salon owner gets that email along with a dozen others that week. Other booking apps write too. So do agencies that want to run the salon's Instagram, and startups that sell an AI phone receptionist. They all use the salon's name and say something nice about its photos. The owner probably does not bother reading these emails anymore.
Social media looks the same. Pangram, a company that makes AI detectors, scanned a million posts. On LinkedIn, more than 40% of the long posts were written entirely by AI. LinkedIn comments were slightly more likely to be AI than the posts. So if you post on LinkedIn, many of the comments you get back are written by AI too.
The other problem is that everyone is busy. With AI, you can probably do what used to be an eight-hour day in two hours. But that doesn't mean you have six hours left. I think people try to do everything at once now. They still fill all eight hours, and a lot of them work even more. There is always one more thing they can start with AI.
Researchers from UC Berkeley spent eight months studying a US tech company with about 200 employees. The company didn't require anyone to use AI. People still worked faster and took on more tasks. They worked more hours of the day, often without being asked. Many prompted AI at lunch or in meetings. One engineer told them, "You had thought that maybe, oh, because you could be more productive with AI, then you save some time, you can work less. But then really, you don't work less. You just work the same amount or even more."
The salon owner does the same. They use ChatGPT for their Instagram captions, their replies to Google reviews and a new price list. Maybe they are building their own booking page. They have no time left to read or answer what other people made with AI.
Delegate tasks. Get software.
