I'm a pretty good developer with a preference for front end. I have access to other like minded devs, and between us assume we can cover the full stack.
What is one thing I, regardless of scope (10 minutes to 10 years), that I can do to have a net positive impact on a global scale?
I used to work at the US State Department (took a funny path), and the most impactful programs I was ever a part of were the scalpels. They targeted one extremely specific facet of...whatever...and then executed.
Where do I go from here?
There are two ways to truly change a society.
1. CHANGE THE POLICIES OF A NATION. This can have an immediate impact. It also means being in politics. I'm awful at politics, so I didn't opt for that path.
2. IMPROVE THE EDUCATION OF UPCOMING GENERATIONS. This is a slower, yet more fundamental way to shift a society. If you can't cure cancer, maybe you can help set up an environment to educate someone else who can. This is the path I choose.
I'm not a teacher. I opted for the education technology (also known as "edtech") industry. Technology isn't a panacea for all the problems you may see in the education system, but since it's a system fraught with inefficiencies, there are many opportunities for technical improvements. The trick is, of course, finding the right opportunity that can also develop into a self-sustaining process/organization.
That was my own assessment, at least. With your experience in the US State Dept, politics may also be a viable path for you. Either way, we definitely need more people like you! Cheers for asking this question.
