The notion that a type system is "just" logic and so should be trivially followed by anyone "smart enough" or "careful enough" is laughable - there are many different type systems (sometimes with different details depending on the options or pragmas you feed to your tooling), and it can take time to get a sense of where the boundaries are.

The notion that you're not likely to find a type system helpful if you have trouble with it initially is harmful.

Please don't do this.

I would've never said "just". Formal logic is big f...reaking deal.

I never said anything about being "smart" or "careful". I only said that hacker types, for whom the ability to subvert anything anytime is a fundamental tenet, tend to have a hard time sticking to the rules of a formal game, whether it is a type system or not. Just look at the reasons Lispers give for liking Lisp.

"Just" was in no way meant to diminish significance; it was meant to draw attention to your improper limiting of scope. Someone "fighting the compiler" is not fighting "executable embodiments of formal logic", but "executable embodiments of formal logic and a pile of engineering decisions". Often, enough of those decisions are made well that the tool can be phenomenally useful; some are made less well, and some simply involve tradeoffs. It doesn't have the... inevitability that your wording carried. Programmers coming from a context where enough of those decisions have been made differently are likely to get tripped up for a while in the transition, without harboring any objections to logic.

True, but you left it up to us to figure out what attributes of "hacker types" were relevant. As there are many different uses of the word "hacker", it was quite unclear that you meant to refer specifically to inability to stick to rules.

While people of that description may well persist in "fighting the compiler" for longer, that is not most of what I've observed when I've observed people struggling with a type system, and I reiterate my assertion that those new to a particular tool and used to doing things another way also frequently struggle for a period.
