As much as one-quarter of deaths in Europe and the United States were once from tuberculosis. People often romanticize what’s rare and look down on what’s common.

How will artificial intelligence (AI) impact people’s jobs? This question has no simple answer, but the more AI systems can independently carry out long, job-like tasks, the greater their impact will likely be.

Take a look at the chart below, which shows solar PV exports from China to the rest of the world.
