This question made me pause and ask another question: Who are the geeks of the early 21st century, specifically, 2014? I fear in my heart that software development is becoming less and less of a "geek" hideout over time.
I did, however, go to Maker Faire last weekend. It was a geek wonderland. There were so many cool projects on display and a huge emphasis on getting you started. It shocks me when I hear people say how "commercialized" and "mainstream" it's gotten -- for me, it seems like the hardware market is just starting to open up to some really cool innovation, and there's a huge community of people doing it right in their backyard.
A more long-term question might be: what's going to be the next "geek" hideout after hardware?
