New housing will be built with media centers. No, not an area to watch media: to CREATE media.
Everyone will be so in love with being a social media "celebrity" that they'll want a "studio" of some kind in their apartment/house/whatever. It'll be like a TV studio, with sets, backdrops, hookups for equipment. Or even the equipment itself, if the place comes "furnished."
Or if the place is building is ritzy enough, there will be staff to do some of the stuff, the same way some buildings have doormen, poolboys, or maid service.
For their media posts, people are going to start upping their productions.
The really ambitious are going to use hoity-toity art direction, lighting, and music. There's going to be pro's selling their services doing the above.
Small-time operators will be super-busy doing production for "Joe Lunchpail" and "Sally Housecoat," who want to keep up.
An ever-growing population is making for an ever-growing pile of worldwide garbage. And just like we used to have megafauna like 3,000 pound sloths because of abundance, we'll soon have giant versions of things that eat our garbage:
Earthworms will dig holes that could swallow a car.
Imagine trying to get to your car late at night, and fighting your way past opossums the size of bears.
Montana Dave already got on the bad side of the local raccoons that were normal-sized, but lived to tell us about it. What if they learn how to open doors?
