Monday: the door. Today: what it learns.

Monday: the door. Today: what it learns.
1 bit.
The cinema door asks "over 18?". The answer is yes or no. No name, no birthday, no ID, no database lookup,
no trace.
That holds whatever you're holding. Phone, watch, card. The rungs differ in height and say so honestly. But
the answer stays 1 bit.
Today we're showing this in Nijmegen, at EUDI Unfold #5. In a cinema. Fitting.
