"She" is not AI, yes. "She" was a person - best netrunner in Night City - and "she" died.Is it just me who thinks that she is not suitable to be called AI? She is a "digitized personality" or something like that, different from AI like Delamain.
"It" - namely, Alt we meet in the game, - is not "she". It says itself that Alt whom Johnny new back in the day - is not around anymore. Now, all we experience is Alt ("it") the AI. Parts of it are of human origin, yes; but the whole - is not a human person anymore. It is much more, and much different, than any human psyche, digitized or not.
So make no mistake (and it's an easy mistake to make, yes): Alt is an AI.
Now, there are several types of AIs out there, mind you.
Some are like Delamain, yes - entirely "synthetic" constructs, consiting of code entirely non-biological in its origin. Those come with wildly varying levels of complexity / ability, and some of them like Delamain are made to intentionally be human-like in many regards, but yet others are not. The latter includes Night Corp AI, afaik, which was created and developed with specific, covertly commercial, purposes.
Yet some others are like Alt - having a part of them being digitized human psyche, yet some other parts like the above. Notably, i think Soburo (after his biological death) becomes one, i.e. Alt is not the only example here.
And yet some others are neither of the above, instead being "area" AIs - a mafifestation of the Net parts themselves. This is more in lore thing which hardly (if at all) gets mentioned in Cyberpunk 2077 in particular, but is well known in Cyberpunk universe lore in general. Those AIs are emergent, nobody ever "made" them. These appear as a result of Net's big parts evolving themselves, though time. Examples are "Pacifica AI" and the AI which is known to exist based on networks existing in soviet space, from what i can recall. Basically, it's Net's routers, switches, hubs and servers which all together give birth to those "not human made AIs" in Cyberpunk universe. Those AIs are very difficult to encounter and interact with, too, as they said to be very much "to themselves", seeing things in much more "introverted" ways in compare to humans, human-made and partially-human AIs.
I.e., just saying some is "an AI" - is far not enough to understand what kind of thinking, sentient, self-aware entity we deal with. And this approach is not unique, too. Other lore universes exists with similar phenomena of "whole range of very differing AIs" in them. Perhaps one most known example of which - is Mass Effect, which had Reapers (collective, ancient, beyond-comprehension AI); Geth (collective, emerging, man-made AI much within comprehension); VIs (various interactive systems having often rudimentary, but sometimes advanced, self-awareness); man-made individual AIs of various complexity and purpose; Normandy's AI (initially purely "ship's brains", but later developing into quite a person); etc.
