To say that Japan's population will shrink over the next 83 years is an understatement. According to official state figures, the country will go from about 126 million people today to about 50 million in 2100, a 60% plunge.

Moreover, the makeup of Japan's population will utterly change, too. From about 15% of the population, people 65 and older will be 35% in 2100. And the working age population whose salaries are supporting the old will plunge: in 1970, Japan had 8.5 workers to support every retired person; in 2050, the number will be 1.2.

As you see in the chart below, these numbers reflect the trend in most of the world. Right now, the median age across the planet is around 29. In 2100, it will be 42. When you exclude Africa, the whole world will be, on average, 60 or older in just over three decades.

All of which is to say there is good reason for the development of elderly care robots. Many robot companies are focusing on just this area of development. Among them is iRobots, the makers of the Roomba robot vacuum. Watch this video of iRobots CEO Colin Angle, speaking to Axios about how the elderly can "age gracefully in place."

What can robots do? Either now or soon they will be able to:

  • Take grocery orders and pick them up
  • Keep the house tidy
  • Check vital statistics and report when things go wrong
  • Provide company of a sort
  • Supply chauffeur services

President Trump told the New York Post on Thursday that he plans to deliver his Republican National Convention speech from the White House lawn, despite bipartisan criticism of the optics and legality of the location.

Why it matters: Previous presidents avoided blurring staged campaign-style events — like party conventions — with official business of governing on the White House premises, per Politico.

Antibody drugs and various medicine cocktails against the coronavirus are progressing and may provide some relief before vaccines.

The big picture: Everyone wants to know how and when they can return to "normal" life, as vaccines are not expected to be ready for most Americans for at least a year. Two therapies are known to be helpful, and more could be announced by late September, NIAID Director Anthony Fauci tells Axios.
