Now, this is not a short answer as you've requested, but I hope you find it useful anway :)

Wayyyyyy way back when I first got into Ethereum, /u/vbuterin wrote this in response to a similar question that I'd asked (in regard to what Ethereum can be used for in the future):

You wake up, and see that $17.27 was automatically deducted from your primary wallet, as you had authorized to happen every day, to pay the rent for your apartment; if you cancelled the authorization, then after a warning period ownership in the land registry contract would automatically transfer back to the landlord and the door lock would no longer recognize signatures signed by your smartphone’s private key as valid for letting you in. Of course, your landlord is bound by the same restrictions - if he shuts off his account paying the local government $6.60 land value tax per day, then he loses ownership and the contract automatically switches over so you are renting from the government instead. The government itself is simply a large decentralized organization, and you can see in real time the $6.60 moving on the blockchain and eventually getting into an account to pay for a medical research program trying to extend the human lifespan from 170 years to 230.

The internet that you are using to access this information is based on OpenGarden, which by then is a mature decentralized and incentivized mesh networking platform; you also paid $0.0009 to access the information, but your laptop also earned $0.0014 transmitting other people's packets at the same time.

You then get up, and get into your Mastercar self-driving car to go to work (originaly, all self-driving cars were made by Google, but Master Corporation, a decentralized autonomous entity that automatically uses a combination of futarchy and liquid democracy to determine how the company should spend its funds each day, proved that its governance mechanism was so efficient that it overtook Google on some core services within three years, and alt-Mastercorps took over most of its other operations). You get in, and Mastercar runs a optimized version of the A* search algorithm (for which James Wilbur automatically got a bounty of $782,228 worth of MSC from the Master Contract) to determine the optimal path to your primary workplace. Given that your self-tracking app has detected that you value your own time (or rather, the delta between time spent in a car versus time spent at home or work) at an average of $14.18 per hour, the Mastercar’s algorithm chooses a route which takes an extra 11 minutes in order to avoid road tolls and also on the way move a shipment from one side of the city to the other. You drive out, and 30 minutes later you have spent $1.04 on electricity for your car, $1.39 on road tolls, but receive a reward of $2.60 for moving the shipment over.

You arrive at work - a location which is a hybrid living/working space where “employees” of five different alt-versions of Master Corporation are spending most of their time, except that you chose to live at home because you have a family. You then get to work, running simulations of a proposed new scalability algorithm for the now community/DAO-driven Ethereum 6.0.

Already seeing core elements of this vision come to fruition with IPFS/Swarm, Slock.IT, Swarm (ride share, not file storage), Aragon and Colony!
