I only saw the 1st part, and the essential content of the conversation was:
A - I like to hear more about what you said about speakers.
B - Is the speaker distinct from the sound emitted by the speaker?
A - I think we must first make a distinction between speakers. There are human speakers and human-made speakers.
B - But, is the human speaker essentially any different from the human-made speaker?
A - Well, of course, there are many kinds of human speakers, like good speakers and bad speakers.
B - Yes there are, so that raises the question - can the bad human speaker produce a good human-made speaker?
Philosophy, as understood by most people and philosophers, is a slightly more intellectual form of gossip.
