I don’t think AI is as advanced yet so we’re not able to tell. I mean sure it’s problematic. And oftentimes down to circumstancial evidence.

But I regularly spot posts here which start with an affirmation, they’ll follow the rule of three, they contain em-dashes and have the tendency to be quite unnecessarily verbose for the amount of information in them. It’s not too hard to spot.

Similarly with PRs which contain a lot of bullet lists and emojis. And then Claude has some own style. You’ll spot it after you went through enough AI code. It also sometimes states the obvious. Like add a comment on how the main function is the main function. And sometimes you’ll see nonsensical code or it not following project sturcture or other things due to some limitations in the process.

So I wouldn’t say “we can’t tell the difference”. But it ain’t easy. And it’s time-consuming because AI output looks legit on a first glance. That’s the intent behind it.
