I don't think this "effort" argument for technical knowledge pieces makes sense to me. If there is something I need, I do some research and I look for signals of authoritative information. I don't really care about how much effort it takes to write a blog post.
Even if, on the most good-faith scenario, someone did all the research them told an LLM to add more pizzazz for some reason, there is still a chance that the LLM hallucinate a lie here and there that the author might have skipped when proof-reading if they proof-read it at all.
I can't trust a machine specialized in generating convincing bullshit.
For starters, if you're writing something yourself, it's not "zero-effort". It might be low-effort, but you still put some effort into it. And low-effort doesn't mean worthless, as you illustrate ("but if someone needed that information...").
Consider that the refrain seems to be: "I won't put more energy reading something than you put into writing it". A "quick" post takes little energy to write, and little energy to read. That's fine!
If you put in zero effort on some programming knowledge, they would be to put in the effort to confirm that you're correct.
AI to an extent removes a lot of signals that in the past people used to figure out if the writer spent effort on the writing (length, lexicon, grammatical correctness, you name it).
Personally as long as whatever is there is not full of load bearing seams I prefer to give the benefit of the doubt even if the "voice" sounds AI (and TBH it feels the "AI voice" issues are mostly "opus pre 5.5 voice" issues, talking to gemini does not feel very "AI", same as fable, opus 5.5 occasionally has its load bearing moments but nowhere near as much.
