Many African countries have had successful domestic tech scenes for longer than most people realize. That includes robotics communities, network operator groups, Linux user groups, ICT associations, and more. There are a lot of incredibly talented and dedicated people here who have been tirelessly building these communities for a very long time.
Sub-Saharan Africa started to become hip about three years ago. Ever since then we've been practically drowning in hackathons and other feel-good tech events organized by "movers and shakers" from the west.
I'm ranting a bit, so don't get me wrong; all of these projects have a positive impact. I'm just sick of hearing about how "innovative" some people are for doing stuff that's already been done before just because they're the first people to yap about it on-line.
