Most AI developers do not have your style of thinking. If they did, they would be forced out of their job positions.
You seem to be living in a fairy-tale world. Look, if Google/Meta/etc manager's decide that their AI development teams should consider processing of PDFs a top priority - because they believe it is economically justifiable - then AI will learn to correctly interpret the majority of existing PDF documents within just a few years.
No, I'm living in reality.
It's not a matter of LLMs processing PDF files being "economically viable", it's about the optics of these massive, money sucking pits of nothing we call "artificial intelligence", being advertised as the answer to ending famine and replacing the entire job market, yet they cannot something as "simple" as read a PDF written in Comic Sans, 12 point font, no graphics, with all of the text written at a 45 degree angle, because they aren't trained on anything but English
and only when it is written left to right. That's too difficult for them.
You say "that's not a big deal", I say "it demonstrates 'false advertising'." It doesn't matter what LLMs are
supposed to do, only what they
can do. Results determine their value.
What do you think will happen when the enormous data centers that are being built right now will go online over the next few years? Do you believe that AI models are going to become dumber because of that - or are going to become smarter because of that?
That depends on the time scale. These data centers are being built on the back of the "promise" of AI, its supposed 100x ROI. They are built with VC funds and there is
still no product. A product generates revenue and these models do not generate revenue―certainly not enough to justify their upkeep. The problem, that no developers have solved thus far is, "what do people do with our models, that generates profit?" Like, Grok and Claude have a lot of utilities, but do those utilities even
begin to make enough money to cover their operating costs? Or are they basically subsidizing an unprofitable venture?
Eventually, either these companies start generating revenue from people
voluntarily paying for services with their models' utilities (because you cannot strong arm people into using your product forever) or the VC capital will run dry. Like, the prevailing theory among tech bros right now is, if customers cannot hide from AI (because it is everywhere and literally impossible to avoid), eventually you will submit and be compelled to use it. Right now, society is still negotiating how much "mandating" it is willing to put up with, but in due time, we will cross the rubicon and then either people will give up or completely reject it. There is no half measure with AI. Either it's ubiquitous or it will find a stable market, but it will not be so omnipresent. It can't be both.
