Given the extremely large spectrum of "technical content" available for someone to focus on, can you provide more detailed examples of what would be higher quality technical content in your opinion?

BTW, I'm not disagreeing with you at all as I too agree. I'm just wondering what things you also see as missing.

I find most user content is focused on the introductory level, which makes sense if you are attempting to appeal to the largest audiences for income (so not faulting anyone). I often see content on data engineering but most just define "data engineering" and at most talk about things high level Hadoop, Spark, etc. and do not provide any examples/patterns of working with data that is even close to representative to what I do in my day job. The same is true many other technical disciplines too. With a couple notable exceptions on some security topics (such as demonstrating certain exploits), and some hardware topics -- such as Ben Eater's great work (https://eater.net/)

Oh, one other exception as others already pointed out, conference talks are also very good. Though I think they miss the heart of your question (I could be wrong).
