Amazing, and very affordable, home automation systems, especially related to mood and lighting. You know, keypad or ID front door entry, multiple awesome automated window shades for every mood/weather condition/time of day, with star cutouts, digital displays to tell me when it’s a good night for stargazing, amazing aurora borealis-type mood lighting over the hot tub in the bathroom ;) haha you know. Some kind of a white pod desk which embraces you and helps regulate your mood and relax you with light/music/aromas?? as you work. Some way of having a completely safe campfire in the backyard in places where the laws don’t allow it, and/or of having a yard twinkle with thousands of candles at midnight on the summer solstice…without spending a fortune on stupid wires or broken bulbs or having outdoor plugs put in or on the energy itself.
Uh, probably not a super helpful answer. Quality of life stuff.
