Lots of people working on securing the oceans, air and land. But who is securing the subterranean? Good, cheap and fast tunnel boring robots will help us secure supply lines in warzones (drones will get you if you go above), solve traffic, transport desalinated water, deliver packages directly to your apartment building in minutes, etc.
Make it easy to have more babies! How do we make it easier to conceive, deliver, and raise children? Essentially building the foundations for 1 Trillion Humans across our galaxy.
I fundamentally believe in the right to self defense. But guns seem like a primitive way of defending yourself and your family. Sure given the technology we have, they are the most cost effective but we should make guns that are non-lethal but neutralize evil instantly. Like: instant temporarily paralysis, tranquilize, etc.
We should think of food from first principles. Also, we should make really good food for astronauts!
Why are clothes so boring? Feels like we have regressed. Why don't the big designers make more technologically advanced clothes? I wanna see Off White Iron Man Nanotech Hoodies, Tom Ford bulletproof men's suit, t-shirts covered in solar panels, full camouflage quarter zips, indestructible shoes, Dior skin tight overalls for Amazonian exploration such that no insects can bite you, etc. at the Met Gala. (like edna from Incredibles)
Midjourney is already so good at designing novel interior, furniture, clothes, accessories, etc. Now how do we productize this? Maximize experimentation, chaos, and beauty. Fight back against mass manufactured standardized slop (IKEA)!
