If reality is a data structure, can the simulation theory hold up?

Exploring the idea that objects we perceive in everyday life do not reflect objective reality.

  • Professor of cognitive science Donald Hoffman presents his theory that the world we perceive is a virtual reality. Hoffman has tested this theory by running successful computer simulations that suggest there is no objective reality.
  • When it comes to Nick Bostrom's simulation theory, Hoffman agrees with parts and disagrees with others. Hoffman argues that, while space time and physical objects do not correspond with objective reality, conscious experiences like the smell of garlic and the feel of velvet cannot be produced by the simulation.
  • "You can't start with unconscious ingredients and boot up consciousness," Hoffman says.

Participatory democracy is presumed to be the gold standard. Here’s why it isn’t.

The hackable technology that worries even a legendary con man

Before we release new technology into the ether, we need to make safeguards so that bad actors can't misuse them.

  • Right now cybercrime is basically a financial crime — it's a business of stealing people's money or stealing their data. Data has value.
  • We develop a lot of technology — we need to always ask the question how the new innovation can be misused and make safeguards so that it cannot be done.
  • Because we currently don't do these things, we have hackable vehicles, pacemakers, and laptops.
