It's shockingly dangerous and should be illegal.
In this case, explicitly mentioning the antibiotics abuse and how that leads to resistance would've made a big difference in quality. Going further and explaining feasible ways about how to deal with it and how to manage the economical and lifestyle impact of possible solutions in a feasible manner would've been even better.
You cannot form a decent realm of discourse when every comment is low-effort. This is the kind of thing that (for now, and only up to a certain degree) separates Hacker News from things like popular subreddits that only chant trendy opinions or act as venting boxes without much actual factual discussion going on.
FWIW I'm just as guilty as the GP of doing the same at times, and I should be called out for it as well whenever it happens. Sometimes we don't know what we don't know, know too much and take things for granted, or can't tell when our biases are showing. It is up to the community as a whole to keep the standards high.
I could go to the nth degree and speak about how capitalism creates a lot of negative externalities, including factory farming, pollution, depression and the current state of the news. In fact take the latter — here is a website for what the problem is, what the solutions are, and how to fix it... as well as an hour long interview that goes into all the details:

I often go into amazing detail and write blog posts about each topic... but if I link to them on HN, I would usually get accused of throwing out “20 claims at once” and “shilling my blog” and my videos and solutions (that I give away for free). You just can’t win with some people...
If you were making a detailed argument about the issues with unregulated capitalism, and I would just respond with "Go read some Mises", it's just a lazy cop-out that doesn't address the problems you're presenting and lowers whatever value the comments may have to a reader, even if I had a point or not.
Downvotes don't change facts. The browbeating over people misusing antibiotics at the individual level is a lot like plastic producers guilting consumers over recycling when the root cause is from industry.
Factory farming uses antibiotics purely for profit, the health of the animals is only an ancillary benefit. Animals fed antibiotics grow larger, driving higher profits. It's a tragedy of the commons situation, since the abuse of antibiotics has major negative externalities for us all, but the profits are reserved for the owners of the factory farms.
We need a UBI funded by Pigovian taxes on pollution and other negative externalities. It’s the only way I can see ending these situations sustainably!
But what if the nano-bots get a virus!
