The Brookings Institution last week published a report from global economy expert Indermit Gill prophesying that the AI leader in 2030 will go on to rule the planet until at least 2100. The territories in the running include the US, China, and the European Union. Economists appear to have reached a general consensus that artificial intelligence is among the four great "general purpose technologies" to come along since the 1800s. Gill argues that AI, like steam power, electricity, and information systems technology, will directly impact the way business is conducted at the global scale by 2030.
