I believe in truth and that facts do matter. I also teach young people. Being a wage earner was not a bad thing, but I yearn for the freedom to live an easier life, eventually. I want that for everyone. False beliefs are traps that hold people back from being their best selves. Carry flat-earth beliefs as a core foundation and look at what differences it would make. Geostationary satellites, and all the tech jobs that go with servicing that sector, just disappeared. Ditto solar. Travel to distant places, and time zones, becomes an insolvable problem. Your co-worker is holding his life back by believing in medieval superstitions.

It is a kindness to challenge people to find what is true.
