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.
Lisp date from 1958 and some would argue that rule-based programming is AI. Eliza is also more than 5O years old.
The ethics of AI have been extensively discussed for a very long time.
In essence, the debate taking place around AI is a heir of the 19th debate on automated looms. Karel Čapek play, Robots, has been written in 1920 and it was already an ethical discussion of "autonomous machines"...
My first introduction to AI and its consequences and dilemna come from Isaac Asimov Foundation Cycle and that dates back to the 1950s.
AFAIK, the 3 Laws of Robotics invented by Asimov are actually used by philosophers & AI practitioners.
(I added and then removed references to the Golem, but...it could be argued as relevant to this discussion)
I am quite vehement in this discussion exactly because I am currently debating whethever or not I should release a new AI software I have designed. From a technical standpoint, I am quite proud of it, it is a nice piece of engineering. From a political standpoint, I feel that tool could be used for goals that I am not sure to agree with...
