For now, but I don’t think this is true for long. There are too many talented people working in this space who care enough to develop solutions to some really difficult problems that blockchains are perfect for.
People have been saying that exact thing for over a decade now, and there still has not been a single compelling use case outside of conducting illegal (or fraudulent) activity. A decade's worth of work from talented, enthusiastic people turning up nothing of substance should serve as evidence that blockchains are not, in fact, going to provide anything revolutionary.
Anyway, the real world use cases are largely large money transfers and scams, and PoS is more efficient for that.
