It's deep in the uncanny valley. Even ignoring the writing style, the entire post is about the incredible insight of "you can build TCP on top of UDP" using a forced analogy. No further analysis, no real world example, just UDP and the convertible and the convertible and UDP...
I felt the same way, which is terrible news for me because I explicitly use double dashes in my (100% human) writing instead of em/en dashes -- explicitly because of the LLM association, but they're evolving
And I think it's interesting that it flags it as confidently AI generated. I also got a whiff of AI and I'm never sure how to take confirmation bias from AI detectors - though that said, I've gotten a whiff of AI before and had this detector say it's confidently human.
Reading this I kept waiting for the... point? I feel like the whole thing was more like saying "UDP is like a convertible because you can strap a tarp on top when it rains". Like... sure? But that tarp is going to be crappy compared to a real roof. And the idea that that tiny layer is "the best of both worlds" is frankly ridiculous to me.
