HN attracts a broad range of ability, but generally upvotes the smartest content. So if you sample from “upvoted HN articles and comments”, the content you read is heavily biased toward things written by unusually smart people. But there’s a range.

By contrast, most companies will attract and hire people like their current employees. So the variance at any particular company is much smaller than in the general pool. Everyone ends up working alongside people like them.

So if you work at a big bank or something, you probably don’t interact with many people like the super geniuses who write interesting articles that get upvoted a lot on HN. They’re over represented amongst HN content, but most programmers are average and getting by just fine. And remember, hotshots are equally ungrounded. Lots of good engineers you meet at Google were hired at straight out of collage. They have no idea how the sausage is made anywhere else. Lots of folks here don’t have your experience. They have no idea what it takes to do software at a company that sees their job as a cost centre. Or what it takes to get good work done in spite of political pressure to stagnate.

Having a variety of voices gives all of us something to learn and something to teach.
