So, what to explain a block after its prior 10-min block is a 38-minute block? Is it a sudden increase of difficulty?
Reading the reply of mocacinno, the probability of when a miner finds the next block depends on luck and the strength of their computers. They keep going through the block headers until they find the correct hash. Could take 10 mins or 30. The difficulty of these task is then adjusted every 2016 blocks.

with such powerful hash rate, will it be used to brute force against our private keys? I guess the answer is no. but since the power of hashrate increases, all private keys will be brute forced. I certainly don't mean now or anything close. But one day.. with quantum computer..
Breaking the entropy of a private key is a very difficult thing to do now, that it is almost impossible as the creation is completely random with high entropy. If quantum computers can break that encryption, then bitcoin would be one of many systems affected, since it is currently more secure than others.
Maybe there would be a security update when that situation is at hand.
