The only reason seems to be so the EU can claim to be a leader in AI regulation; a dubious accolade at best.
I guess one difference between LLM-style AI and most other systems is that when other systems produce the wrong output you can usually step through the code, figure out why, and be confident that the same issue won't happen again.
VC firms have brainwashed people into thinking LLMs are "I" when really, they are XOR'ing GIGO machines.
Because executives, everywhere it seems, are gullible enough to be tricked into believing that A(sigh)I isn't a colossal waste of money and electricity, they are throwing it at every problem, everywhere.
This means that a fucking stupid framework of frameworks designed to turn electricity into heat via compute is being inserted into every single aspect of commerce, banking, law enforcement, warfare, business decision making, and yes, hiring.
The difference between scraping a resume for keyworks and having an LLM evaluate it is that you can look at the list of keywords and understand what it is happening.
A list of keywords is comprehensible and reproducible. You can subpoena a list of keywords. You can modify and control a list of keywords. You can legislate the requirement or forbidding of keyword criteria.
An LLM is just a tunnel of sewage that pours shit out the other end, a black box, a mystery.
But A(sigh)I excels at letting people be lazy and generating an endless stream of dreck designed to addict the gullible so it is going to take over the world.
At least the EU is trying to slow it.
