Why is waterpressure something that is holding us back to go very deep in the ocean?

Would it crush the machine’s we’re using to explore depth? Would the pressure affect a human inside an exploring machine if the machine itself is strong enough to withstand the outside pressure, if so how? Would a full can of coke collapse if we would bring it very deep in the ocean? If so, how? Because what I heard is that a liquid can’t be compressed, so a full can off coke shouldn’t collapse right?

Thanks in advance

Think about diving into the ocean this way: you are laying in bed covered by a blanket. Every foot you dive deeper is like adding another blanket on top of you. Initially, you don’t notice the added weight, but as you go deeper/add more blankets the weight starts to push down on you, eventually add enough blankets and the weight becomes unbearable.

The pressure at the depths you are talking about is enough to crush machines, submarines, and certainly a can of coke. The liquid in the can of coke is not being compressed, it’s the aluminum can. Eventually then pressure being exerted on it is enough to cause the can to crush.
