Sorry but that's bullshit. That would be like disregarding all the engineering that goes into developing a car, just because someone else invented the wheel.

Sure - without that invention they couldn't exist - but real innovation isn't just the foundational features of the product. 99% of the work is in small refinements - for example about two hours a day my Mazda is a horrible car to drive because the sun catches the chrome logo on the steering wheel and blinds the driver. The newer models? They have a slightly different shape on the steering wheel that puts the shiny logo in the shade at that time of the day. It takes real work over decades to figure out tiny details like that. Most of the job is things that aren't obvious when you first have an idea to build a product.

Someone else probably, probably millions of other people, likely had the idea long ago... the real innovator is the one that actually does the hard work to make it a product someone will actually want to use.
