This one sentence sounds very LLMish:

> Object storage as the source of truth gave the economics, and tiered NVMe SSD/memory caches gave the performance.

Yes, that construct is, like em dashes, something that humans have been writing for a long time. That's the problem with triggering on one isolated tic. The tic comes from human practice, it's not like they invented it!

I'm not sure I've ever read a sentence like this before LLMs. Maybe I didn't pay attention, possible. I should do a search of pre-LLM writing for this construction.
