Data from my two years at Software Engineering Radio indicates that technical software podcast listeners are an under-served market. If you are a software engineer who doesn’t listen to many podcasts about software, this should be self-evident.
Technical knowledge about software will help you work more intelligently.
The scope of software engineering is growing. If you use WordPress, Ableton or PhotoShop, you are a software engineer. If you use Facebook, you are a software engineer–you are helping build software. On a twenty year time horizon, there is no “opting out” of knowing how software works. But this is OK because learning about software is possible (and fun) no matter your age, race, or creed.
