Ask HN: Recommend me a course on Coursera

I'm asking because there seems to be an extreme bias towards beginners courses, or content that is rather limited in breadth and depth compared to what a university might teach during a full masters degree.

ie, there's about 50 security intro courses (with lots of overlap of course), one "advanced" course that's been delayed for long and isn't all that advanced (Crypto II from Stanford), but nothing that even comes close to the various full-semester courses covering particular niches that I took in university (for example, we did one full semester course on each of: symmetric crypto, asymmetric crypto, side channels, "special topics" (random stuff), a cryptoanalysis lab, and 3 more niche things - and those are just the pure crypto courses, and even/especially within that area I feel I've barely scratched the surface).

These university courses cover not only more topics than Coursera covers (overall; there are many things even in this niche that Coursera has that we weren't taught, which is neat), but within each we went into considerable depth. In particular we tended to approach them from a rigorous mathematical perspective (number theory, linear algebra, statistics, proofs, etc). My worry here is that Coursera might be more geared towards people that don't need to learn the topics well enough to be actually able to use them professionally, let alone academically. ie, more like edutainment than education (no offense intended. I wasn't sure if I should include that sentence cause it might sound harsh, but I think it illustrates what I'm getting at).

We also didn't have courses that are blatant advertisements (#18568).

I don't want to put Coursera down (quite the opposite), I am genuinely interested in your answer - Is it just me not seeing everything available? Is the field I'm (slightly) knowledgeable about an outlier? Or am I missing the point of Coursera (maybe it's more focused on training industry professionals than academics than universities?) Or is it correct, and if so, is it intentional or unintentional? Is there a single field of study where Coursera could replace a university partly/largely/mostly/entirely? Will there be?

It teaches you mental models on how to think and find a solution to a problem. It explains the concepts behind each model quite well.

Topics include how to determine a valid argument, an iron clad argument, using heuristics to solve problems, among other things.

My only gripe with the course I linked is that it is an audio version of what seems to be a video version on the Great Courses website. You might want to check that out too.
