It depends what you are trying to achieve but there are usually niche corners of any market which are underserved or ignored by the incumbents. While you may never become the top player in the market you can make a decent living in many of these if you find the right corner of the market.

Of course, if your aim is to become a silicon valley bro living on ramen noodles and angel investor tears then you'll need to find a way of disrupting the incumbent, and if your plan is to do the same thing but cheaper you are wasting your time.
