I can think of at least 2 promising areas: 1.Micropayments- currently it's very hard to charge for anything on the internet so we get ads, which everyone hates or paywalls which people hate even more. Internet money doesn't need to be decentralized but then who will issue or build it -google, facebook? So far this is the most promising. 2. Data privacy - everyone's complaining about Facebook now. So far public decentralized blockchains have offered the most promising way to build truly decentralized apps (while still providing an incentive/payment to developers). I'm pretty sure even more uses we can't think of now will open up as the technology matures
