INDESEM - International Design Seminar - is a biennial with workshops, lectures and debate founded in 1962 and re-initiated in 1986 by Herman Hertzberger. This publication reviews and reflects on the 2019 edition of the seminar; explorations on the position of the architect in a rapidly developing, (digitally) connected society. Nowadays, the amount of available knowledge to designers is becoming sheer endless. Whether or not willingly, this forces designers, architects and urban planners to take position in a globalised changing world. By whom or what are you influenced? What is the scope of your work? What message do you want to convey? Who is it precisely you’re designing for? In short, what defines the echo chamber wherein one operates? INDESEM 2019 forms a critical stage to confront students with their respective echo chamber, the extent to which it is perforated or segregated and to (re)define it, based on critical debate.
