Um, well I'll try my best. In a way it's true that it's a solution looking for a problem and I think we are seeing novel ways to use it. I think a problem is that people still associate blockchain with "currencies" and payment. That is a fairly narrow view of an immutable ledger. A project that, in my opinion, gives a glimpse of the direction blockchain will go in is the Baseline Protocol - a joint project between EY, MS and Consensys. I have tried describing it in another comment [1]. But to give a basic idea is that it does not necessarily use blockchain to transfer value, but instead to coordinate two entities. Basically it puts communication between business entities exchanging, for example, supply chain orders on the blockchain. Essentially the blockchain becomes an auditable protocol for communication, reducing technical overhead and making things like adjudication easier.

And here is a more technical example of hooking up SAP to order-matching on Ethereum. It's a little basic, but gives an idea. https://blogs.sap.com/2020/08/21/sap-integration-with-ethere...
