According to the principle of the constancy of the speed of light, we are always moving at the speed of light relative to light, which is the current physical explanation for the irreversibility of time. We have never considered the time dimension when making products, so the products are limited to the reproducible spatial dimension. Satoshi Nakamoto's Bitcoin has created a dynamic and continuously evolving time chain with a dissipative structure based on the time dimension to carry the value of monetary transactions. The uniqueness of life lies in following the irreversible laws of time dimension, rather than staying in the reducible laws of space and becoming a mechanical tool. Whether AI can have autonomy or "consciousness" depends on whether AI products can perceive time, that is, whether they can go beyond the restored spatial law and enter the temporal law to build the technical framework of the product.
