Paula agrees with this and Ashley disagrees, making this the point of disagreement. Paula explicitly makes this claim. Ashley argues that technology depends on unique factors in each setting. This implies that alien technology would develop differently, likely without radios.

Neither speaker makes this claim. Ashley gives legal and political systems as an example of likely differences between aliens and humans. She uses this as an analogy to argue that alien technology would also be different.

Ashley agrees with this, but Paula doesn’t give an opinion. Paula argues that alien technology would be similar to ours based on how math and science work, but never discusses the influence of our cognitive makeup one way or the other.

Paula agrees with this, but Ashley doesn’t state an opinion. Ashley discusses possible aliens in the abstract, but never weighs in on whether intelligent aliens are actually likely to exist or not.

Neither speaker talks about this claim. The discussion is just about whether radio telescopes are likely to find aliens, and doesn’t touch on the broader search for extraterrestrial life or whether we should spend more money looking for aliens.
