OK, somebody should say it: the term 'one-stop-shop' has no place in academic research. Due to their diverse and exploratory nature, there is no single solution for scientific projects - else this would be routine research. RT if you agree, or feel free to argue otherwise below.

The problem with most machine-based random number generators is that they’re not TRULY random, so if you need genuine randomness it is sometimes necessary to link your code to an external random process like a physical noise source or the current rate of US tariffs on a given country.
