“In my experience, Julia and its packages have the highest rate of serious correctness bugs of any programming system I’ve used, and I started programming with Visual Basic 6 in the mid-2000s.”
Biased sampling, wrong integer products and sum functions that silently return garbage. These are bugs in a language sold to scientists. Composability is Julia’s headline feature, and it is also the problem, since packages combine in ways nobody tested. A wrong answer with no error is worse than a crash, and nobody reviewing the paper will rerun the numbers.
