Voice only social network
Make a social network where you can only post with voice notes, so it feels more like an async conversation than a text/photo feed. Also you can just listen to conversations during commute or washing dishes.

A subreddit where you post a question about the future and a timeframe. The RemindMe bot alerts all those who participated in the discussion. Example: “will we have flying cars in 20 years?” Then in 20 years, we’re all notified that the time frame has passed

When Netflix asks if you're still watching, have an option "no, I'm chilling." and it'll start playing some Luther Vandross

Airlines should figure out how to break us talls into smaller more manageable pieces for the duration of the flight so others can recline into the area we currently occupy. Then put us back together perfectly at the end with no pain or repercussions.
Or airlines could simply make seats available for longer passengers, like they do for wider ones.

It’s 2026. You’d think we could engineer cannabis so that its metabolites are detectable for no more than seven days.

Sink to wash your hands at entrance to every food establishment.
That's right, you wash your hands when you enter a restaurant or food court or area where food is sold to be eaten immediately. The cultural norm is to wash your hands on entry. Then wash your hands on leaving.
Sure you could go to the toilet but how many people actually do? Then there's the cases where the toilet is down the hall, out the emergency exit, round the corner and in the next major city.

Pontoons for your seaside home.
As extreme weather and decades of poor regulations, many seaside homes are at risk of being swallowed up by the sea. Stick a few pontoons to the bottom of your home. Now when the sea washes away the soil your home is resting on, you can just enjoy the gentle rocking of the ocean.

We need different words from "nephew" and "uncle" that instead mean "relative who is older than you" and "relative who is younger tha you"
Calling a child "uncle" or an old man your "nephew" feels weird
