Sure, but the similarities are stylistic in nature, very much in Williams’ vein, and, as I said, not an overt musical reference to A.I. (which to me implies a conscious nod).
I find in the memory theme from Disclosure Day the reference to A.I. quite explicit.
See my post above. I adjusted the A.I. video with the track where that melody begins. The DD theme sounds like a fragmented version of the A.I. one to my ears.
But it wouldn’t be the first time that I believe to hear something that noone else seems to hear.
