I don't love how forgiving the web is. We would all spend far less time debugging painful HTML/CSS/JS issues if the web was stricter. I think several billion man-hours would have been saved and human civilization probably more advanced. Also health-insurance costs would be reduced and web-developer lifespan likely increased thanks to less blood pressure.

(Don't think the Rust analogy really holds. npm is worse than Cargo. Of-course things could be better - a blessed standard extensions library: `stdx` with a quarterly update cycle and the crate nightmare will be solved)
