I think this is true <i>at the current tech level</i>. That is, if your product idea <i>is</i> a website or a phone app (as opposed to using these things to solve a problem in some other domain), it&#x27;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&#x27;s the direction to aim for.
