It's 2100

Ideas that may sound crazy today, but which will likely become true after decades.

Human Experience Marketplace
You're afraid of heights. But you would really like to know how delightful it would be to fly using a wingsuit. This experience must include everything: feeling the wind, feeling how soft your body will be, etc. Then you just think that you want to access https://human-experience.marketplace and your brain gadget projects it on your wall, and you can choose which experience you want to buy. You select wingsuit and wait until someone is available. After a few minutes, someone who wants to fly using his wingsuit announces that he wants to sell his experience along with real-time images. He starts broadcasting for you and for those who are interested, then he flies. After you experience flying using a wingsuit without leaving your house, you can also choose to store such experience for offline usage.

Getting a Driver's License
You go to the practical test to get your driver's license. You're asked to sit in a chair and put on some weird helmet. The helmet stimulates your brain to run traffic simulations and analyzes its responses, which show how you would actually drive a car in real life. After that, you get your results instantly, and all requests from the helmet and responses from your brain are stored in the government database along with your approval/denial attestation.

Real-time Death Announcement
You ran out of time; you're dead. Your smartwatch, which knows you by your biological patterns, detects the cold temperature of your body and your blood pressure to attest your death to an API using its built-in TLS certificate, which notifies the stakeholders and delegates access to all your accounts to your husband/wife.
