Thank you for mentioning this. You often see comments like the OC that are dismissive of articles and seem to think people doing one thing know everything about that thing. I guess when people get to a certain level themselves, they forget that others have to learn things too and don't implicitly know all of the things that you know. I really do appreciate seeing your comment gently reminding people that learning is a thing that has to happen and should be encouraged.

We used to learn all this stuff by word of mouth back in the day, and it's been interesting watching young developers "rediscover" these things on YouTube, etc. Its great because now these techniques are part of public discourse rather than known only by a few.

There is an XKCD for this https://xkcd.com/2501/ , and I have yet to find a subject it isn't true for.
