American GDP per capita climbing as Elon Musk's annual tweet count also climbs. The economy and the timeline, both adding more output every year. The graph is, this once, almost a portrait of the era.
US GDP per capita grew from about 56,000 dollars in 2015 to over 70,000 by 2022, helped by post-2008 recovery, pandemic-era stimulus, and inflation. Elon Musk's tweet count grew from a few thousand per year in 2015 to over 35,000 by 2022 (post-Twitter acquisition tweets included) as his platform engagement expanded dramatically. Two completely unrelated lines sharing a window because the same eight years inflated both a national income measure and a single-individual posting volume. Different units of output, same era.
The country got richer and one CEO got more verbose. Two completely different output curves on the same calendar.
