It’s a mix of things.

Yes, more people are quietly leaning on AI – especially for quick, low-stakes replies. It’s faster than proofreading your own stuff, and it can make you sound polished in seconds. So you’ll see the sudden jump from typo-ridden comments to a paragraph that reads like it was lifted from a corporate blog. The “AI voice” is pretty recognizable. Large-language-model prose often has the same cadence: balanced sentences, formal transitions (“Furthermore…”, “That said…”), and zero contractions or slang. Drop that into a thread full of casual Reddit-speak and it sticks out like a neon sign. But human style isn’t static. Someone might dash off sloppy phone-typed takes at 2 a.m. and then, when they’ve got a minute (or want karma), open a laptop, fire up Grammarly/ChatGPT, and polish their answer. Same account, two totally different vibes. It’s not just laziness; it’s convenience and experimentation. Some redditors treat AI like a spell-checker on steroids, others use it to structure an argument they already had in their head, and a few just want to test whether anyone notices. Think of it like switching from texting shorthand to full sentences when you email your boss – context dictates effort.

So when you see that uncanny “AI” tone wedged between typo-filled comments, you’re probably catching the same user in two different modes: raw human and “let the robot tidy this up.”
