Abstract

The Computers Are Social Actors (CASA) theory is the most important theoretical contribution that has shaped the field of human–computer interaction. The theory states that humans interact with computers as if they are human, and is the cornerstone on which all social human–machine communication (e.g., chatbots, robots, virtual agents) are designed. However, the theory itself dates back to the early 1990s, and, since then, technology and its place in society has evolved and changed drastically. Here we show, via a direct replication of the original study, that participants no longer interact with desktop computers as if they are human. This suggests that the CASA Theory may only work for emergent technology, an important concept that needs to be taken into account when designing and researching human–computer interaction.

That should tell you more about the energy intensity of a long-haul 777 flight.

That doesn't seem like a good way to generate "random" numbers, since it will only produce numbers with exactly two prime factors.

Could you explain it? Those two links are Greek to me.

Reminds me of: "We do these things not because they are easy but because we thought they would be easy."

Nope.

As a point of comparison, the orbital velocity of ISS is 17,000 mph.

The max speed of Unity was given as Mach 2.88. The speed of sound varies from 340 m/s at sea level to 200 m/s at 120,000 feet. So Mach 2.88 would correspond to somewhere between 1000 - 2000 mph depending on where it was attained.

To enter orbit, a vehicle must be simultaneously at orbital altitude _and_ at orbital velocity (in the correct direction).

Furthermore, note that quoting speed as a Mach number is fundamentally only relevant to atmospheric flight. Mach number is referenced to the speed of sound, and sound does not travel in the vacuum of space.

The Virgin Galactic vehicle shoots up to very high altitude but then simply falls back to earth.

You should be able to fall asleep in less than 15-20 minutes without using melatonin as well.

Now there's a name I have not heard in a long while...

Of note, these are the translations of the transcripts. The original transcripts unfortunately were not preserved.

Agreed. I've rented a Tesla on two occasions (for one week each time) and was unaware of this manual release until now.

Has _any_ of his work been successfully replicated?

What is this?

RIP Nat Geo ?
