正確な乱数はどうして必要なのか?

Title Why are accurate random numbers necessary? [Why Math.random() isn't enough] Overview Do you think Math.random() is sufficient? In fact, there was a case where a Russian criminal group beat casino slot machines by "predicting random numbers." "Appearing random" and "truly unpredictable" are completely different things. Cryptography, scientific simulations, games—the quality required of random numbers differs depending on the application, and the wrong choice can lead to real security incidents. This video clearly explains "why accurate random numbers are necessary," from the mechanism of pseudorandom numbers to quantum random numbers.
