So far, blockchain usability is looking very good as authors before me stated and counted a few of already successful projects. I have a strong feeling, that the year 2020 will be strong in blockchain development.
Also, changes need to be done in the industry sector, which is a "driver" of progress. Some of the current processes are based on old theories and practices but because of lack of flexibility in this sector, everything is moving slow. This sector is at risk for disruptive innovation which is in my opinion blockchain.
I am also now for a few years in a development team which we would like to simplify processes and make it more cost-efficient with the help of blockchain. So far looking very promising
