In the world of signal processing there are a lot of technical areas that are super important/lucrative but few people have expertise in them. Often it takes not only technical competence but years of experience. To make this example even more specific, maybe you are good at writing fast decoding algorithms for new telecom standards. There is also a lot of now low-hanging fruit in compressed sensing for the mathletes/computer people who know what that's about. Edit: Actually, just learn math if you're looking to get ahead and have an advantage over many people. This advice doesn't make for the best blogpost or YouTube video but it's effective.
