(I guess people who can do any amount of coding are going to be smarter in aggregate than people who can't, but you know what I mean)

what they'd manage to do is turn it into an O(n^2) operation: pull out *all the rows*, check the *one row* you're interested in, repeat both steps for *every* row

people used to working in hex saw assembly languages as an extravagance that would sissify the next generation of programmers, people working in assembly said same of compiled langs, etc

personally I think anyone who doesn't know at least one level down from where they're working is reckless bordering on dangerous

webdevs should know enough C/C++ to have intuitions about how their languages are likely implemented and be able to read the implementations if needed, C devs should know their archs' assemblies, etc

this is perfectly reasonable to demand of ppl imo, expecting everyone to know "everything" under them (chip fab? EE?) probably isn't
-
but anyway the real issue is once more "programming" shifts from writing compiled/interpreted languages to offloading more work to machine learning frameworks they have zero understanding of the math behind
-
where they have some inputs and some desired outputs and as far as they know everything that happens in between is a magic black box because hackernews told them they don't need to know linear algebra

and these people are easily >90% of the field lol
