A visual introduction to big O notation

Whenever I read content like this about Big O notation I can't help but think the real solution is that computer science education should take calculus more seriously, and students/learners should not dismiss calculus as "useless" in favor of discrete math or other things that are more obviously CS related. For example, the word "asymptotic" is not used at all in this blog post. I have always thought that education, as opposed to mere communication, is not about avoiding jargon but explaining it.

> students/learners should not dismiss calculus as "useless"

This seems to be quite a bit of a strawman to me.

ML is such a major part of the field today and at a minimum requires a fairly strong foundation in calc, linear algebra, and probability theory that I earnestly don't believe there are that many CS students who view calculus as "useless". I mean, anyone who has written some Pytorch has used calculus in a practical setting.

Now in pure software engineering you will find a lot of people who don't know calculus, but even then I'm not sure any would decry it as useless, they would just admit they're scared to learn it.

If anything, I'm a bit more horrified at how rapidly peoples understanding of things like the Theory of Computation seem to be vanishing. I've been shocked with how many CS grads I've talked to that don't really understand the relationship between regular languages and context free grammars, don't understand what 'non-determinism' means in the context of computability, etc.
