I can order food from hundreds of restaurants and have it delivered in less than 30 mins with the tap of a button.
I can book flights and hotels with the tap of a button.
I can play with friends in virtual reality and actually sweat.
I can watch a live stream of SpaceX launching reusable rockets in space.
I could buy a car that is almost fully "self driving".
I can exchange value with anyone in the world anonymously and with no delays or censorship thanks to cryptocurrencies.
I can land in a completely foreign city and get step by step directions to wherever I need to go.
I can translate almost any language in real time, be it in writing, spoken or taken from an image.
And so on...You can (and most of the time do) get paid to build interesting things. It's just that most of us are unable to look at the big picture and not realize that the combined effort of a team is more valuable than the sum of the individual efforts. And if you do actually work on stuff you don't find interesting there is enough demand that switching is not that hard.
And if you want to solve puzzles for the sake of solving puzzles then there are plenty of resources for that.
Plenty of choice in my honest opinion.
