You do understand “never do it yourself” implicitly applies to a commercial/production context, right? Nobody is stopping you learning or choosing to enter the field (to make it your sole professional focus).
It certainly comes across like people are discouraging others from even learning about it.
Just read through this thread and see how few people are saying anything like "you should still learn how cryptographic primitives work though". It's almost nothing but negativity and discouragement.
The blog post in question (which I wrote) literally opens with a link to https://www.cryptofails.com/post/75204435608/write-crypto-co... that encourages people to learn about it! Yes, even if that type of learning means (privately) writing crypto code.
Why would you expect the comments about it to argue in favor of "still learning" when the blog post never advocated against learning? They aren't making this point because I didn't make the contrary one, so there's nothing to argue with.
That you're only seeing negativity and discouragement is a cognitive distortion. I'm not qualified to help people with those, but I hope pointing that out might help you see that the world isn't against you.
That software developers presently and generally are bad at understanding cryptography doesn't mean it's impossible to learn, or that you should be discouraged from learning.
Alright that's fair, in this thread there's not much reason for people to encourage learning it so it wasn't a good example to use. Thank you for helping people to learn more about it.
That being said, the sentiment around rolling your own crypto that I see in the rest of internet in general still strongly discourages any kind of curiosity, intentionally or not.
In other places where it's discussed and in the comments on this thread which are not a direct response to aspects of the blog, you get mostly the same kind of response.

That’s what the “implied” part of my comment means.
