I think the future will be awesome with more technology.
Its both good and bad, good that we will have more advantages but bad if people abuse them and rely on them too much.
No, no big event is going to happen, bad things are already happening now like the disasters happening in countries today so i would say its just going to get worse.
The future without oil will be bad, we use oil for food, cars, and more so without we're in big trouble but i hope we find a way.
I think the future looks like the picture i added below, a apocalypse where nothing good happens, i mean I'm not a dark person who sees the negative all the time but I'm wise enough to see the next step so i know its going to be bad.
Big invention? i hope to see flying cars and flying hoverboards that could improve transportation
