Pick an idea and roll with it, most of them won’t work, but the only way to find out what will is experience since nobody is going to tell you the truth about money making methods.

That’s difficult when there are lots of people who will say that and be serious about it. No way to know if it’s hyperbole.

But the meme is making the more extreme claim that no uses exist, so any counterexamples mean it’s untrue. Not the best way of criticizing companies that don’t know or care what a technology is good for imo.
