2023 – The first test-runs of a superconducting maglev test line, called a hyperloop, are carried out in Datong, China (50 km/h of ~1,000 km/h). Hyperloop One conducted the world's first test carrying passengers in pods, reaching a speed of 172 km/h in Los Angeles in 2020, but reportedly abandoned the goal of transporting humans as of 2023.

In this way, every logic statement can be encoded as its own number.
