> Veering ever so slightly from the common, but entirely non-documented, approach makes it hard to get help. Places like StackOverflow are increasingly useless: instead of answers you get “Why are you doing this at all?”, “Yuck, you’re doing it all wrong, but I won’t tell you why” [...]

While I disagree with the premise (that using old approaches should still take you just as far (and further) 20 years later), I do agree with this particular quote.

Often on SO I see well-supported answers like, "that's because you're doing it wrong" without going into detail on what doing it right would mean, or better yet, suggesting alternative frameworks or patterns where what's "wrong" over here is "right" over there.

If programming in 2018 has become more like plumbing, then plumbers in 2018 have become more dogmatic, and less willing to steer novices that prefer tools like 'x' towards approaches that use tools like 'x' more often.
