Facebook and Libra are focusing on Financial area. Is there any other area that blockchain can be used?? It's hard for me to imagine anything else.
blockchain will focus on areas that require fast payments and low fees. It is possible that businesses in different countries want to cooperate and exchange products, they will use blockchaind technology to make money transfer faster with a much cheaper fee than bank deposit or visa .
That's the maximum use of blockchain and in the future, most large businesses have to use the blockchain.
