I dont remember where but I recall that Cloudfare dont use computers to generate random numbers because its literally impossible. It is always mathematics so its predictable , hard yes but predictable. Instead Cloudfare uses lava lamps movements and calculate that , as it is very random. I will look for the article so don’t take my word for it.
Dude thats not realistic at all. The industry is moving that way and all companies have to follow , if companies dont do they will eventually die , just look at Yahoo , AOL , Phillips , etc barely surviving and nothing what they used to be. Why? Mostly because they were complacent and stay conservative not innovating fast enough.
