The blockchain / big data / Cloud Everything / LLM hype is largely a solution (the thing being hyped up) looking for a problem.
I hope that's clear.
The problem isn't the hype in and of itself. It's that there's a disproportionate amount of hype for things that aren't actually that valuable. I don't begrudge people for being excited about technology, only for being excited about excitement (and forgetting to actually solve problems for businesses and consumers).
