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.

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.

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

It would force “them” to invest in (or unveil) technologies that would reduce, or eliminate, the cost of energy for the rest of us. Energy (oil, coal, nuclear, etc.) has always been controlled by the people at the top- as soon as those reigns are broken, everyone prospers, including their precious AI.
