> I have worked with people who are "fullstack" with Javascript + Typescript, but do not even know what a CPU core is.
Now, this is the opposite of the point that you're making, but i have to admit that it's pretty cool on some morbid level! The fact that we have abstractions that are strong enough for them not to leak and make people dig into the details (e.g. the JS event loop being all that they need to think about).
That's also why tens of millions of people out there can work with spreadsheets of text processing software without knowing what a compiler or interpreter is, or even caring much about the benefits of dynamic linking vs static linking.
Similarly, i can write SQL against a DB without knowing anything about the RUM conjecture or really much about anything apart from the very basics of ACID (at least before Oracle fails to plan queries correctly and needs either statistics to be regenerated or hints added for the optimizer, because it's an evil piece of software).
It just works. I'd argue that it's the way things should be - working on the JVM should absolve one from thinking about compile targets and worrying about things like whether the CPU is from Intel or AMD, or what the ASM format is or whatever. Working in the browser might as well absolve one from worrying about most platform minutea as well, otherwise nothing would get done.
Is is still nice to have a bit of curiosity and explore those things, there being some merit to that, which might as well not be immediately apparent? Sure! Is it required for those people to truly be specialists in their own niche and to be safe from people making fun of their other shortcomings online? Absolutely not!
