♫"That Old Black Magic Has Me In Its Spell..."♫
One has to wonder: exactly WHY the primary emphasis here is on "AI", and "neural networks"?
The only obvious--and also. at the same time, very subtle--reason is "pandering"; pandering to the fact that "Artificial Intelligence" and "neural networks" are subsets of that very large set of current psychological 'trigger words' which are, for the most part, meaningless and totally misunderstood by the majority, even of the very technically and scientifically astute, but which generate, almost automatically, a large number of "clicks"--and hence, revenue--for the publication.
[Other "click-bait-generator (CBG)" words/phrases include, but are not limited to, "quantum computing" (the REAL biggie right now, even though its supposed experts cannot even define it); "machine learning"; "cloud computing"; "room-temperature superconducting"; "super-string theory"...well, you get the idea. And yes: sadly, when some 'author' encounters 'writer's block' simultaneously with a looming deadline, (s)he will trot out that oldie but goodie, sure-fire, CBG: cold fusion. ]
The second point is similar to the first--the use of Unicode as the 'perpetrator' of the indignities highlighted here. This is simply one more use of a 'buzzword' to generate page-clicks. As many of the comments here have pointed out, all forms of trickery were performed with existing code-sets long before Unicode became a 'thing'.
"Extended ASCII Character Set" simply doesn't have the same ring to it as "Unicode". Nor the CBG potential.
