Well I don't think that's what the complaints have been about. I'm not sure if the complaints are even true but is definitely a more common view on HN these days. It's less what you say and I think more "people in X will do all this for an annual salary of about $1,000" so that's the end of the game now. As far as the "pace of technology change;" I don't really see that. I don't count the rather comedic constant wheel reinvention in the JavaScript community really counts as really "technology change" or even think the Web mvc framework du jour rises to that level. So, ok let's look at general cs, what I see is fairly incremental changes in distributed systems, file systems, and so on. Ok let's consider the machine learning craze, but this has been a utilization of 50 year old methods in a much more distributed fashion -- the people who wrote the Statistical Learning textbook in the 70s probably don't think of this is as mega technological change, maybe more like "well, this is finally popular." So I dunno.
