Does "randomness" actually exist?

Think about it, everything that are perceived to be random are just the result of individual occurence happening in a specific order. We call a phenomenon "random" only because of our inability to monitor all these individual occurence.
If humanity ever become omniscient, concept of randomness will just straught up dissappear. But are there things out there that are truly random?

I think a layman's definition of "random" is more along the lines of odd and unexpected. So, technically, nothing is truly random because it doesn't happen without a cause, but in practice, a lot of things seem to.

Quantum mechanics is probabilistic. So the numbers you get when you measure the positions of electrons are random.

Classical physics are entirely deterministic. For quantum physics it’s a toss up and the answer to your question depends on it. That’s really all

That they are probabilistic is already worrying. I wonder how the world will react when they finally crack it and if it is revealed even quantum mechanics are deterministic

What do you mean "crack"? Even theories extending the domain of QM like QFT don't try to explain away the randomness. Searching for a classical explanation of QM might be misguided.

yes randomness exist, you know it, you felt it and you experience it everyday. Omniscience does not exist since knowledge can't travel faster than light. Lightspeed is the limit because we are made out of complex light, so unless you change the definition of the human being you will never be able to change the fact that we can never measure how exactly light behaves.

but what not many people know is that there are degrees to randomness and it's the interaction between multiple randomnesses(?) of different degrees that gives rise to something we call order.

It's currently impossibly hard to know anything with infinite precision. So for all intents and purposes, yes. Randomness exists.

Random is matter of perspective by definition. When you don't have a clue about the generator, stuff is random. When you have, it's not.

Well, there isn't single proof that nothing can travel faster of light, also, speed of light is sufficient for omniscience.

Actually you don't even need to travel to be omnipresent.

Nope. First cause principle states that everything happens for a reason.

That's Laplace's demon. Which, if you think about it, would need a mind of the size of the universe or even bigger to hold AND process information about whole universe, so that would require an alternate universe or some shit.
