By what year will humanity successfully develop the first 'digital person'? This is defined as either an emulated human brain or an artificial general intelligence system with cognitive abilities equivalent to, or surpassing, those of an average human adult. The development of such a digital person does not necessarily imply the creation of a superintelligence, but rather an entity exhibiting human-level intelligence and cognitive capabilities.

The recognition of this 'digital person' as such must be validated by a consensus of leading experts in relevant fields, including neuroscience, artificial intelligence, and ethics, ensuring a comprehensive acknowledgment of its cognitive and sentient status.
