Is AI taking over human brains? Man using AI for work says 'I have started mimicking LLMs'. Internet replies 'you are not alone'

As artificial intelligence tools become part of daily work and communication, a quiet shift may already be happening in how people write and express themselves. What started as machines learning from human language now seems to be going the other way too, with some users saying they are beginning to sound more like AI without even trying.

A simple post on Reddit has brought this idea into focus. A user, who said they rely heavily on AI for work and learning, shared that they had started noticing changes in their own writing style.

In the post, the user explained that English is not their first language and most of what they learned came from movies, articles and the internet. But recently, AI tools have taken over as their main source of information. “I suddenly realized I have started mimicking LLMs style for a while,” the user wrote.


He added, “I have started using the patterns like ‘It is not x it is y’ or so.”

What stood out more was not just the pattern itself, but the awareness of it. The user said they could now “clearly tell” when something they wrote or said had been influenced by AI. That realization, they admitted, felt a bit strange. “AI was supposed to learn from human,” he wrote, “Now, it is started to going in reverse.”

Many say they are seeing the same shift

The comments section quickly filled with people saying this is not an isolated experience. One user responded, “It’s not just you, it’s me too.” Another added, “I’ll be direct, no fluff: you’re not going insane, you’re just getting linguistically fine-tuned.”

Several others pointed out that this kind of shift may be natural. As one comment explained, people tend to pick up language patterns from what they read or hear the most. With AI becoming a daily tool, especially for writing emails, messages and even casual replies, the influence may be unavoidable.

A user noted, “It’s natural to learn from the things you encounter regularly. If you want to not sound so much like an AI, read a range of different styles of books.”

Is this new, or just a repeat of old patterns?

Some users tried to put things into perspective. They argued that what is being called “AI style” may not be entirely new. One comment pointed out that these structured ways of writing have existed for a long time, but are now being noticed more because of overuse. Another said that AI learned from human writing in the first place, so in a way, people are just picking up a more standardised version of language.

There were also lighter reactions. One user joked about catching themselves using words like “however” too often in emails, while another said they have started saying “that’s a good question” before answering anything.

At the same time, a few comments showed concern. One user wrote that constant exposure to AI-style communication could make it harder for people to distinguish between human and machine-generated content. Another warned that over time, it might affect how people think, not just how they write.

Some described it as “code switching”, where people naturally adapt their language depending on who or what they interact with. Others called it a feedback loop; the more you use AI, the more you start sounding like it, which in turn makes communication with AI smoother.
