The way this sounds is that you are more concerned about politics as in people who take party positions and may feel excluded as a group when the majority of the community takes a different position. This is a slightly different issue i.e. party politics, and I think it is fine/a good thing, but it is also important to distinguish the two. This should essentially be under the same umbrella as personal attacks, as they are essentially the same thing.
I don't know whether that is politics or not but I can't imagine discussing Amazon Go as a technology without having that discussion. In fact when you look at HN very little is about particular technologies. Most of our discussion is around the implications.
A talk I recently attended by a data scientist from Amazon had him gloating about how many jobs he could eliminate.
Ironically, the only speaker who brought it up as a major social problem we'll have to tackle is someone from Uber. His solution was less than satisfactory, but at least he recognized the issue.
I don't want to pretend we live in a world of algorithms without consequence.
Yes, what we do can have consequences. We need to think about that!
I have friends working for weapons manufacturers. They don't gloat about building stuff that can blow children up!!! Why the hell should we be absolved from any moral consequences for our acts?
I am not equating elimating jobs and kill children, but I would prefer if our industry abstained from any thought on the consequences of its trades.
I once had to choose between working for a weapons manufacturers for a very nice salary. I chose not to work for them. But I thoroughly thought about it and I don't blame my friends for making a different choice. I politically object to that choice, but it does not mean I am some sort of white knight...and it does not mean that sometimes in the future, if presented with another opportunity, I wouldn't make a different choice...
Anecdotally, I had a neighbor who programmed the guidance systems for bombs, and the only reason I remember him is because immediately after introducing himself as such, he followed up with, "But I'm not the one who's dropping them. By making them smarter I can save lives".
I think that no matter how technically intelligent a field's operators are, they are still subject to the same dissociations as everyone else.
