The way you get around this type of crap is by diving deep, and when you think you've gotten deep enough, go further. Academia, for all it's faults, is a fantastic way around the bullshit you get with industry hype, by mere virtue of open peer scrutiny. You want to understand whether the current "AI" hype will last? Research and understand the theory and academics behind it - therein lies your truth, and if it doesn't align with what you see in industry, you know it's grift. Hint: it's usually grift.
Once you've identified the grift you can rest easy knowing that eventually it will collapse and the grifters will be left with nothing but society-warping amounts of money.
