I think this is true at the current tech level. That is, if your product idea is a website or a phone app (as opposed to using these things to solve a problem in some other domain), it's unlikely to be worth doing. I think the next big opportunities will come with the next technological breakthrough (Internet of things, robotics, AI, nanotech, whatever) and that's the direction to aim for.
