Astronaut
Becoming an astronaut remains one of humanity's most exclusive achievements. Fewer than 600 individuals have ever travelled to space, representing approximately 0.000008 percent of all humans who have ever lived. The selection criteria include advanced degrees, exceptional physical fitness, and psychological resilience that exceeds normal human parameters.
Even experiencing astronaut-adjacent activities requires substantial resources. Space tourism, whilst theoretically available, demands financial outlays exceeding most individuals' lifetime earnings. The astronaut remains fundamentally inaccessible to the overwhelming majority of humanity.
Social Media
Social media represents democratisation of communication on an unprecedented scale. Any individual with access to a smartphone or computer can establish a presence and potentially reach billions of fellow humans. The barriers to entry hover marginally above zero, requiring only basic literacy and internet connectivity.
This accessibility has transformed formerly voiceless populations into content creators, commentators, and cultural influencers. A teenager in rural Indonesia possesses the same technical capacity to reach global audiences as major broadcasting corporations.
