Sometimes what you think is just an illusion. If you can change your thoughts by yourself you hold more power in your mind than any supercomputer in your pocket. Sure you're master of your own mind, but only to a certain degree. The answer to the question: What's real change? is only accessible to the one who comprehends. This is not an answer to the questions that we need a computer for, it's just one of the answers that the computer cannot give us. It's still the same. It's old. It's a lack of comprehension of the difference between the things that change and the things that don't change.
