I meant a never ending stream of sophisticated ideas and precise data that leads nowhere. I used to watch every interview of the guy[1] and .. I always left the video empty minded.
[1] he seemed to have human values and of course knowledge about the topic
Ok, we're going down a rabbit hole here, but just to clarify, you meant "pub talk" as in the kind of conversation people have at a pub after a few beers? Or "public talk" as in a public speech, as nikofeyn suggested?
i can see "overengineered pub talk" as a specific critique instead of them meaning public. i am probably wrong there. but the point still stands as it's rude and not important to make a mention of their english, especially when it seems what they meant is one of two things, both of which make sense.
