I think most idealist people here would be utterly crushed by how bad the situation is in some countries. Going in with ideas of how tech will be used to raise everyone up... Then having to live in camps with armed guards outside because there's frequent raids... No way to even get supplies in because corrupt beaurocrats keep asking for bribes. The same beaurocrats who are supposed to be on the side of their country are also massively part of the problem. Then you end up realizing that there's so many problems and inter-dependencies that it's not clear if any single person can do anything positive.
All aboard the FEEL TRAIN. Yeah, its hard, I wish I knew the answer.
