I had a similar experience with my sister in law who is getting her programming degree this month. When I asked her what was her final project and some details about it, she told me the entry point to her frontend was Angular. When asked how it was served and how it got to the browser, all i got was confused looks. When I showed her that the first thing that gets to the browser is an HTML file that then loads Angular and her application, her mind was blown.

I had a similar experience with a family member. When I asked them how their keyboard strokes appeared on the screen, all I got was confused looks. When I showed them that the first thing that happens is a hardware interrupt, her mind was blown. Seriously, it's okay that people don't know the ins and outs of every little detail. Abstractions are useful, until they're not. And then when they're not, you go figure out the level below. Even the most advanced, most skilled front-end devs spend 99.99% of their time not caring that the browser loads an HTML page.

  I think your analogy would be valid if the previous commenter had, for example, asked their sister-in-law how the browser interprets the JavaScript it receives, or how it builds the display from the DOM. Now that would be asking about irrelevant and unnecessary levels of detail which are best abstracted away. However, knowing that the process starts with the browser receiving HTML over HTTP is essential to understand what's going on, even if you know nothing about the details. If I may, a truly similar experience regarding keyboards would be this: I had a similar experience with a coworker. When I asked him how the code that he types appears on the IDE on his screen and not on that of any of our colleagues' screens, all I got was confused looks. When I showed him that his keyboard is wirelessly connected only to his computer, which runs the IDE, and his computer is then specifically connected to his own monitor via a cable, his mind was blown.

    It was just a random example, you can literally pick any level in any number of abstraction stacks that exist and make the same analogy. Sometimes it becomes necessary to know how the level below works. That doesn’t mean it’s a requirement to be affective at the level above.

      I would categorize things as "does someone on the team need to know this": * Why does a key appear on the screen when I push a button on my keyboard: no * How is an HTTPS connection created: generally no * How is the JavaScript library deployed: 100% yes You might be able to throw something together that works without understanding that it is a JavaScript library with a bootstrap HTML page but if no one on your team understand that you will eventually need to find someone that does to solve a problem.

        > * How is an HTTPS connection created: generally no I would think that people doing web development probably benefit from a working knowledge of DNS, TLS, and PKI. Without those, I would expect a lot of readily avoidable problems with HTTPS. In general I advocate that software engineers should have a functional, if abstract, understanding of how computers work on various levels. They might not need a detailed understanding, but people often benefit in unexpected ways from understanding the systems they work with.

        In 2022 that person is ops not dev. None of my devs have any knowledge [1] about TLS, DNS, or even TCP. The only interaction devs have with the messy outside world is Rack/WSGI, their DB ORM, their Queue/Job abstraction, and the AWS client libs. [1] Not like they literally don’t know but that their code has no interaction with it.

  Not knowing how Angular bootstraps is how you get super huge SPAs that take forever to load on anything that is not a gigabit connection. Technical details matter.

    Genuinely do not follow this logic

That may say more about her than CS in general. I remember my very first encounter with Angular I made my seniors investigate how the hell double way binding could even work that way to have them confess to me that yes, we had 40k repeating functions running every n seconds to check variable states... for a static website whose double binding was just a first render time convenience. No wonder our mexican clients with shit phones couldnt load the site as well as our iphone-heavy Hong Kong ones. And it was my very first day on Angular. How can she not be curious, Angular is so wrong and magical, it blows the mind to understand how it builds all that magic. Maybe your sister in law is the kind of persons who laughs at magic tricks ? I d be raging mad myself, I prefer to avoid them or Ill just be obsessed until I understand them

Man that is really sad, but I suspect these code in the cloud schemes will be targeted toward hordes of developers with such a superficial grasp on what’s happening.

I like an SPA pile on as much as the next person, but I've seen similar ignorance from asp.net webform developers many years ago. Some of those were even "experienced" developers.

  To be fair, ASP.NET Web Forms obfuscated the relationship between your code and the HTTP request-response cycle almost as badly as an SPA framework.
