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.

Political activism may get people invested in politics, and affect urgently needed change, but it comes at the expense of tolerance and healthy democratic norms.
- Polarization and extreme partisanships have been on the rise in the United States.
- Political psychologist Diana Mutz argues that we need more deliberation, not political activism, to keep our democracy robust.
- Despite increased polarization, Americans still have more in common than we appear to.
So much for rest in peace.
- Australian scientists found that bodies kept moving for 17 months after being pronounced dead.
- Researchers used photography capture technology in 30 minute intervals everyday to capture the movement.
- This study could help better identify time of death.
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.
