I am not sure that statement is always true. It is safe to say that without *distributed solutions*, very large scale networks become unmanageable, and AI technologies can be used to support distributed solutions.

Let's take a specific example: the CASM work in the IETF. One approach to massive scale support of address and prefix management is a massive centralised database and an old-fashioned (NETCONF/YANG style) mechanism to push allocations out into the network. Another approach is a large set of distributed autonomic prefix managers that request new space from a distributed address pool when necessary. The second one is definitely a target for machine learning, in order to set optimal parameters for the individual prefix managers.

It will help where the problem can genuinely be tackled by "divide and conquer", for example where localised optimisation and localised repair can help. But when localised solutions are inadequate and traditional centralised solutions do not scale, AI can be the answer.

Agreed.
