(edit, i misread the score: after removal of the em-dashes the result is 48% generated and 49% assisted, add the sources, then it is 33% generated, 36% assisted, and 30% human. i didn't check the original text including the sources. i ran out of free credits.)
(edit: turns out it doesn't help as much as i thought it would. see the edit above)
In my opinion, this construct is massively overused by LLMs and is extremely jarring to read. The pithy followup "The delay is the weapon." feels like Year 8 Debate Club and is very melodramatic and cringy, which LLMs do a LOT.
There are other spots that stand out, but this is the point where I said to myself "oh this is the point where the author stopped "cowriting" and just pasted the LLM slop directly."
Around Opus 4.6 release it got good enough people tried laundering it all the time, and around 4.8 the group dynamics were such that it was worse to call it AI writing than launder it as your own.
Regardless, there was still enough of a taboo around it that the way people would try to launder it began to often include an AI-generated "sources" table, which was also aggressively bad, but lord knows no one reads those. So it was just another sigil that misled.
