Whenever articles like this bubbled up, I used to want to delve right in to satisfy some inner need to be deeply knowledgeable about the craft. I don't feel that way anymore now that I'm in my 30s, something flipped. Now I'm much more interested in higher-level abstractions and building complete products that solve some real problems, rather than occupying myself learning about the nitty gritty details of how software works under the hood.

I think it's maybe nice to know how we interact with memory in software (memory allocation/deallocation, naybe how manual memory mgmt is done, something about garbage collection?), but that's about it.

I feel the same wayy now that I'm older. The nitty-gritty of some of the memory management stuff just isn't relevant. The work I'm doing now is at a different scale and I let the language designers worry about this. It is still useful to know some details as they apply when I'm programming, but a lot of this stuff just doesn't command my attention!
