The blockchain is super useful as a business backend. Two ideas come to mind:

• More games like Splinterlands
• Remittances. This continues to be a huge market in Latin American countries where people often leave to the United States and wire dollars back home using outdated remittance services like Western Union.

I wouldn't mind if HIVE stayed niche for the social aspect but I think it has huge potential as backend solution for business. I agree that education might be another industry.
