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

Liquid can be compressed but much less than a gas. Double the pressure on a gas and its volume halves. Even at the deepest part of the ocean, water is only compressed by 5%. This would be enough to compress a coke can, even ignoring the fact that full cans contain some air.
