The way I've put it before, is that a culture issue (in something of a soup of them) is that "people" aren't an "interesting technology" that will, for instance, make HN headlines or provide interesting things for technologists to work on or brag about, so SV companies don't really invest in "people" to solve problems. SV companies under-value important labor roles like customer service, and instead over-value automation and algorithms.
A common argument is that people don't "scale" quite like automation and algorithms do, but we have millennia in expertise in labor markets (humanity survived quite a while without algorithms pretending to be customer service) that we could do much better, if so much of SV wasn't about avoiding and/or entirely shirking labor costs for "shinier" technology solutions.
