"Everything has been invented or considered" is not even close to what I said. I literally do it for a living -- I only work on new products. I said that OP does not have a novel business idea for other people's companies that have (collectively) 500,000 people working for them. It's wrong to say that no one will invent anything again. It's also wrong to say that, without deep/insider knowledge of a company, that you are smarter and more creative than 100% of their employees. It's laughably arrogant and/or naive.
