If humans could fly in cars that travel at speeds of mach 4, that would be neat. If humans could find a way to travel faster than the speed of light in space-ships… that would be neat. If humans could eliminate poverty, that would be neat. If humans could eliminate aging… that would be neat. If humans could eradicate ego-dystonic homelessness, that would be neat. That is all I shall write at this time, for now.
