Idea Business
There's this notion that there are a limited number of business ideas and all of the good ones have been taken or are depleting. This is similar to the idea that the resources on our planet are taken or are depleting.
In the modern world where the cost of execution and building keeps going down, it is all about ideas. It is humans who are able to create new ideas which are valuable.
There are companies that are building tools for asteroid mining and spectral imaging technologies to discover the unlimited resources that are available to us across the universe.
Creation of new knowledge is what creates value. Creating 'new' knowledge isn't easy.
