I understand about 3 words of German and I found that video fascinating. Like Russians from 1970 touring a Western supermarket or something.
I understand more than 3 words of German, and the money quote, by Döpfner, appears at the 6 minute mark:
"What I would hope... that we do not try now to play from now on the cliché of a super cool Silicon Valley guy [laughter]. Let's really keep some sort of decent German spiessertum."
The term "Spiessertum", and the German "Spiessbürger", refer to people with a particularly narrow-minded mindset, determined by extreme conformism and opposition to change.
"Babbit" or "Babbitry" may be the closest English terms to capturing the whole meaning.
