endanger humanity

Misuse by Machines

Fully deployed web of things

”Machine intelligence is not human intelligence.”

- Chris Welty

Acceptance of machine intelligence

investigate fail-safe approaches

discuss "acceptable machine behaviour" before it's too late?

Discuss! Miel Vander Sande [@Miel_vds]
