A robot butler to haul me out of bed. Sweets with zero calories. Kids on the subway with sensible emotional states. My cat.

Seconding teleports. No more gasspewing deathmachines. Instant travel across the world. Also, ftl capable terraforming ships. So we could start colonizing everything

3D glasses that clip over your existing spectacles Large but lightweight items like big packs of paper towels with handles on the packaging Soundless but powerful vacuum cleaners A looser fit of ladies jeans whose pockets are feasible to use for storage The elimination of straws.
