Last summer, the singer Akon announced that Akon City – the ‘real-life Wakanda’ that he planned to build on the Senegalese coast – was being abandoned. When ground broke on the project in August 2020, he seemed confident that it would transform 136 acres of mangroves and low scrub into a gleaming metropolis. ‘I plan to retire in that city,’ he told the BBC. ‘I don’t like to use the word the king of the city. But that’s what it will turn out to be.’ When I visited a few months ago, the only part of it that had been half-built was the welcome centre.
