The price of renewable energy has fallen 99.8% since 1975 [1] and power generation from renewables has increased 800% since 1965 and doubled since 2010 [2]
GDP per capita is 5-20 times higher than in 1820 [3]
Life expectancy has more than doubled since 1770 [4]
Armed conflict causes just 0.2% of global deaths [5] and relations between nations have become more peaceful since 1945 [6]
5 billion people own smartphones [7], which are orders of magnitude more powerful than a supercomputer of 50 years ago, and which they can use to access the entirety of human knowledge in the form of books, articles, and free lectures from top universities, plus instant communication and collaboration with people across the globe. These are all things that the richest people in the world didn't have access to for most of human history.
