I don't mean it as an attack on GP, but no, I don't agree that this is pedantic. This happens constantly when science is popularized -- people read one article and leap to the conclusion that a problem has been revolutionized/solved/answered simply because they're reading about it -- and no, the HN audience is no better. Technophiles love a good scientific revolution story.
It's very much a fundamental misunderstanding of how science works. Almost nothing in science has an answer, and if you let your brain lock in that way, you forego the opportunity to ask interesting questions. It also leads directly to lots of downstream pathologies common in amongst laypeople (e.g. "The Science is Settled", which it almost never is).

I am not an expert in this field, but others have evidence too. Particularly when asking "why" questions like this, the bar for proof is incredibly high.
