Air Quality: Despite the continued progression of climate change, and proliferation of wildfires, air filtration is seamless for most indoor environments. A cheap air quality meter syncs with industrial purifiers, regulating PM2.5 intake below the cognitively harmful level. Though the improvement to quality of life is nearly imperceptible, the change adds an estimated $2Tn to US GDP annually.
Pandemics: Similarly, outdoor air quality is managed by cheap 3d-printed negative-pressure helmets which have the side-benefit of preventing essentially all airborne disease in public settings. Privately, we still have to rely on testing, but it’s only $5, relatively non-invasive, and easy to perform from the comfort of your home.
Bluetooth: Bluetooth just works. Not the way XKCD predicted, but actually better. Once opened, the AirPods Mini Pro S simply connect, immediately and painlessly, to your active Apple device.
Food: Improvements in flash freezing enable produce that’s always seasonal, delicious and ripened on the vine instead of in-transit. More general applications mean fully prepared meals, available at a moment’s notice, and designed for your taste. It’s the frozen TV dinner from the 50s, except, you know, actually good. Compact countertop combination air-fryer/microwave/steamers mean that food is always cooked through evenly (no more hot pocket magma). Again, all from the comfort of your home, no need to gear up to go outside, and no depressing Blade Runner 2049 vending machines.
