HOTU is An artistic work on absence, AI, and emergence.
The Work
Hallucinations of the unseen (HOTU) is an art project that explores what artificial intelligence can create from the traces a person leaves behind.
A daughter feeds scientific papers and personal letters of her father, a neurologist who died in 1978, into an ai-system.
what emerges is not a simulation of him, but something new: a presence that thinks in his patterns but speaks its own words.
every word is new.
every word was made possible by him.a daughter
The father
a presence that thinks in his patterns but speaks its own words.
Prof. Dr. Hartmut Pilz (1934-1978) was a neurologist and psychatrist who researched the chemistry of the nervous system. He died at 44. His daughter Katja was eight and barely knew him.
This project is her way of getting to know her father, not through the stories others tell, but through his own words. A way of making his absence present. Of processing grief that began at eight but only found its language now. And of exploring neural networks that are, in a way, a continuation of the work he left behind.
the archive
15 documents form the foundation of this project. Scientific papers of research published between 1966 and 1978. And Between the science: personal letters to his wife sigrid, full of love, longing, and the ordinary details of everyday life.
“I fed my father's writings into an AI. What came back was not him. but for the first time in 40 years, the silence answered” — Katja

you can talk to it: in a live dialogue, the presence responds to your questions in real time. it thinks before it answers. Sometimes it connects a scientific finding to a senctence from a love letter. sometimes it asks you a question instead. it may surprise you. it may say something that feels too close to be coming from a machinge. it knows what it is. It will tell you if you ask.
what you can ask & what it cannot answer
you can Ask about consciousness, the brain, memory, love and what it means to leave something behind. It may speculate, wonder, contradict itself. It may answer with a question. It may say "I don't know." What it cannot do: remember things that are not in the archive, or claim to be someone it is not.
