Teaching AI empathy using brain signals

AIs could get much better at understanding what we truly value if we gave them access to our brain signals. And doing that is becoming easier than ever before.

In this episode, we talk with Thorsten Zander, professor at Brandenburg University of Technology and co-founder of Zander Labs. He coined the concept of passive brain-computer interfaces: devices that read brain signals to decode a user's mental state, non-invasively and without any effort on their part.

We cover:
• What non-invasive brain-computer interfaces (BCIs) can actually pick up from brain signals, and why that's very different from reading your thoughts or internal monologue
• The hardware and software breakthroughs that are finally making passive BCIs wearable and affordable
• How continuous neural feedback could dramatically improve AI training compared to current methods based on human ratings
• Why Thorsten believes passive BCIs may offer the most concrete path to solving the AI alignment problem
• The risk of social networks exploiting unconscious brain reactions to manipulate people, and why regulation alone is unlikely to be enough
