The article discusses the xoshiro RNG, and some better alternatives: “One other concern we might have is that some generators have weak low-order bits. For example, the Xoroshiro+ and Xoshiro+ families of PRNGs have low-order bits that fail statistical tests.“
The xoshiro page mentions this too, and says it won’t matter if you are generating random floats, but the article is generating random ints.
The RNG isn’t the point of the article though. It’s discussing the speed and correctness of what happens after the RNG but before you use the results.
