That's also called "constructive feedback" or "having something useful to say". OP offered his thoughts on the best cases where this technology could be applied while explaining how Parkinson actually works and how this limits the usefulness of this solution. If this is "such an HN reply", then this is also the kind of reply for which I come back to this site.

There is literally not a single sentence of "constructive feedback" in that post. Just a post being a typical HN complainer about how since it's not perfect it won't work. He did offer his thoughts on the "best cases" but he did it in the most typical dick head know-it-all way. There was nothing positive about his post when something like this is only positive. I'm shocked you come to this site for that type of comment when there are so many great comments that actually contribute and actually offer constructive feedback.

Lets just be clear... He recommended BRAIN SURGERY rather than a simple "hack" spoon.

Well, so would I. The spoon doesn't cure the symptoms.

I don't know the exact numbers, but I definitely feel like brain surgery carries a much higher risk with it than a new spoon. Some people might prefer not to take that risk, especially in cases of elderly people who may not be strong enough to survive surgery.

Well, so what? It seems to be a standard medical practice. It only sounds scary because it's new / we're used to have it sound scary in TV shows.

It also sounds expensive.

Brain surgery is very risky, invasive, and is only available to a subset of the population. Spoons are risk free.

A small amount of "constructive feedback" drowned out by the excessive pessimism that one can only find in HN comments. Let me also mention that we don't live in a world where everyone can(or even wants to) get brain surgery.

Excessive pessimism? All he said is that this "will not be as useful in most cases of Parkinson's disease" because <list of reasons>. For me this is clear thinking, not pessimism. If one is not able to handle this kind of feedback without going emotional, then one most certainly lives in the world of self-induced delusions.
