Maybe some people have matured a bit more than "hey, new tech, cool!" and think a bit more about it critically. The AIs are hallucination machines, not knowledge machines, by DESIGN, so it's a bit hard to remedy.
This is exactly what I'm talking about. You don't understand well enough what they are (even AI researchers don't, so have some humility), but you do latch on to one of the few elements in which this new tech is imperfect, ignore the enormous impact it already has in its fairly infant form, and pooh-pooh it and everything slightly like it for the remainder of the existence of this universe.
Think about tasks like speech recognition, image recognition, OCR, translation and all the other tasks that these "by DESIGN hallucination machines" have blown previously existing tech completely out of the fucking water. Is that 'hallucination'? 'Useless chatbots'? I can now give one of them an image with a visual joke and it does a pretty good job of explaining the joke.
Critical thinking is not just being jaded and contrarian, you know.
The gobs and gobs of R&D money are up for grabs from opportunists everywhere, they're not always good investments.
No shit, Sherlock. That wasn't the fucking point. Again you latch on to some imperfection in the stated and ignore the main thrust of it. The dot com boom and the early days of the internet also saw fucktons of bad investments and grift. Yet the web grew like a motherfucker because of all the money and research that was well spent, now didn't it?
Also the ridiculously old and proven technique is expensive and doesn't scale, so now you have the costs of both humans and machines.
Oh, now whether it scales is a criterion? Way to move the fucking goalposts. Damn this new approach, it only increase productivity by 50% instead of exponentially.
As to how expensive it would be: you clearly have no experience with these AI systems, or you are being willfully ignorant. Getting AI to generate shit for you that is 80% OK and getting that to 100% of what it would have been if you had done it yourself is trivially cheaper if that saves you a fuckton of time. I have been doing this almost daily for the past couple of months with fairly complex matters. It is very easy to see how a bunch of Excel banker grunt work can easily be made much cheaper by doing the same. Even if each employee stays on and just checks their own AI-assisted work thoroughly.
