6G has the potential to realize the ambition of an autonomous network at maturity level of 4/5 (high to full autonomy) and transform networks to embrace Self-X and Zero-X capabilities, unlocking innovation with resilient, high-quality services at massive scale, real-time agility, and at a more sustainable, lower overall cost. The role of the network operator in 6G will transition from automating network functions to collaborating in a continuous dialogue with the network, to define goals, validate outcomes, and sustain trust in cognitive and fully autonomous networks.
