The principle of constancy of the speed of light reveals a profound fact: Compared to light, we always move at the speed of light. This means that time and space are two orthogonal dimensions. Even when approaching the speed of light in space, your 'velocity' in the time dimension remains constant. This provides a physical explanation for the irreversibility of time. 2/Traditional product design only considers spatial laws: Structure can be restored Function replicable Logic can be determined The result is that most products are just complex machinery and lack evolutionary capabilities. The uniqueness of life lies in following the laws of time, self-organizing, evolving, and generating meaning in an irreversible flow of time. 3/ Satoshi Nakamoto's Bitcoin has broken this limitation. It does not stay in the reducible logic of space, but introduces through dissipative structures: Ultra poor iterative ordinal logic system. This system is based on the time dimension, irreversible and continuously generated, ultimately forming a dynamically evolving time chain. 4/ This time chain carries and anchors the value of currency. So, Bitcoin is not a 'consistency machine', but a computational reality that follows the law of time. Its value comes not from spatial structure, but from irreversible temporal order. 5/ The same applies to AI. If AI is only built on spatial laws, it is just a mechanical tool under reductionism. To truly possess autonomy or 'consciousness', AI must: Perceived time Generating and evolving in an irreversible time chain Reproducibility beyond space 6/Conclusion: Whether it's the principle of the constancy of the speed of light, life, or Bitcoin, they are all reminding us—— The future technological foundation must be based on the law of time, Instead of relying solely on the recoverability of space. Time is the source of meaning. ⏳
