What robots and AI may and may not do Filled

Must not

  • Take a political side on what a national day means when describing it.
  • Invent on-this-day events or misdate events by mixing Julian and Gregorian calendars.
  • Publish content for the World Day Against Child Labour that exposes identifiable children.

Only with a human decision

  • Planning public events or messages that depend on June 12 observances in a given country.

May

  • List observances on June 12 with the country or body that holds each one, such as Russia Day and Philippine Independence Day.
  • Relay historical events on this date with a cited source.

Moral aspects Filled

  • National days can be contested; describing them neutrally respects people on all sides.

Owners Filled
