"Self-driving cars prove to be labour-intensive for humans: Building the road to autonomous vehicles requires a lot of costly manual input," by Financial Times' Tim Bradshaw in S.F. (subscription):

  • "Most companies working on this technology employ hundreds or even thousands of people, often in offshore outsourcing centres in India or China, whose job it is to teach the robo-cars to recognise pedestrians, cyclists and other obstacles."
  • "The workers do this by manually marking up or 'labelling' thousands of hours of video footage, often frame by frame, taken from prototype vehicles driving around testbeds such as Silicon Valley, Pittsburgh and Phoenix."
  • "[H]umans will still be needed behind the scenes for many years to come, drawing boxes around trees and highlighting road signs, in order to keep these systems fresh."

President Joe Biden vows to be "a president for all Americans"

Moments after taking the oath of office, President Joe Biden sought to soothe a nation riven by political divisions and a global pandemic, while warning that "we have far to go" to heal the country and defeat a "virus that silently stalks the the country."

Why it matters: From the same steps that a pro-Trump mob launched an assault on Congress two weeks earlier, the new president paid deference to the endurance of American political institutions.

President Biden has delivered his inaugural address at the Capitol, calling for an end to the politics as total war but warning that "we have far to go" to heal the country.

What's next: Biden and Vice President Harris review readiness of military troops, a long-standing tradition to signify the peaceful transfer of power.

Joe Biden and Kamala Harris were inaugurated as president and vice president respectively in a ceremony at the U.S. Capitol on Wednesday morning.

Why it matters: Top Democrats and Republicans gathered for the peaceful transfer of power only two weeks after an unprecedented siege on the building by Trump supporters to disrupt certification of Biden's victory. Trump did not attend Wednesday's ceremony.
