Going to Space

Aren’t we spoiled that just 50 years after the Moon landing many of us pretend that space travel should be ubiquitous?

The history of innovation is not linear. After an idea becomes applicable, and before it spreads reliably, and affordably to a large number of people, there can pass a lot of time. It took 500 years after Leonardo invented it, for helicopters to be practical. It took hundreds of years for transatlantic travel to be safe after Columbus discovered America. But if you want to experience space travel in a way already today, you can do it through an analog: go scuba diving!
