Well one of the first things is that it allows people to have fresh prepared food whenever they want it, a busy single mom with a headache can still serve her kids a meal cooked from fresh which means she'll won't even need to have expensive instant meals or unhealthy quick to prepare things, it'll be a huge money saver especially when it's easy to combine home and locally grown produce plus it'll be much easier to maintain a healthy diet.
For me personally being too busy or too tired to cook soon turns into a bad cycle of not eating properly, feeling bad, eating worse... if I could ask my oven for lunch suggestions and it'd say 'your daily protein requirements aren't met and your blood sugar is low, we have the ingredients for these meals you enjoy...' it would change my life
Biggest problem we have is global warming, we already have the tech needed to solve it, it just isn't being implemented.
If we don't implement the tech we have to solve this problem, some VR goggles or hyperloop podcars (or whatever) aren't going to have any return on the investment.
Solar shields at Sun-Earth L1... that would require SpaceX type tech, no? Pretty much all other energy tech, although significantly better than oil and gas, also affects the climate of the earth if done on a large scale over a long period. Thermodynamics is a bitch.
Thermodynamics actually makes basically everything carbon neutral other than digging shit up from the ground and burning it.
We just gotta stop digging up hydrocarbons out of the ground and burning them which releases gasses into the atmosphere which throws things out of balance.
Hydroelectric dams, Solar Panels, Wind Turbines, even nuclear power plants don't do that. Sure solar and wind wasn't economically viable until recently (they definitely are now though) but hydro and nuclear have been around a long time. It just burning fossil fuels was considered to be cheaper until we were aware of the true economic costs of it, which is immense.
