I think part of the deal with groundbreaking ideas is that people don't see them coming and/or think they're bad ideas until someone proves them wrong. Another problem is that you're not aware of all the fields that are changing. It's not just going to be all sexy CPUs and GPUs all the time, but for example, things like low-cost, decent density solid state LIDAR is going to be huge pretty soon. We've seen prices for LIDAR go from as much as a house to low four figures today and if Velodyne et al. achieve what they want, even three figures in the next few years (velarray, velabit, plus competitors). Cheap computers are going to be able to see in 3D in high fidelity soon; even robot vacuums have some LIDAR now. Look at what patents are expiring, what fields are being juiced by macro moves in the industry (e.g. LIDAR with autonomous driving), and look for problems that are becoming or already are expensive and currently have no or just cumbersome solutions in the market at the moment.
