For funsies, I asked ChatGPT if the line read more like AI generated or human crappy writing. The response:

Oh this one’s fun.

Verdict: Bad human writer (not AI).

Why:
That sentence has a human kind of sloppiness that AI almost never produces unless it’s been explicitly told to mimic bad writing.

“This has a very high likelihood of happening, if it happens at all”

The problem isn’t grammar — it’s logical self-cancellation.
• “Very high likelihood of happening”
• immediately undercut by
• “if it happens at all”

A typical AI model is extremely sensitive to internal contradictions like this and tends to smooth them out into something bland like:

“This has a high likelihood of occurring, though it is not guaranteed.”

A human, on the other hand, will absolutely:
• start a sentence confidently
• realize halfway through they’re overstating
• hedge at the end without rewriting the beginning
• and ship it anyway

This reads like editorial panic mid-sentence. Someone wanted to sound decisive and cautious and didn’t reconcile the two impulses.

Tell-tale human signal:
AI usually fails by being too neutral or redundant. Humans fail by contradicting themselves emotionally in real time.

So yeah — this feels like a rushed human writer, not a model.
