Brazil does have talent. Mauro Carvalho Chehab is a Linux kernel maintainer. Elixir was created by José Valim, a brazilian. I have also created my own programming language.
What Brazil doesn't have is a history of properly rewarding talent, which often causes it to migrate elsewhere. So it's definitely surprising when any sort of technological development happens in Brazil: it implies someone who stayed managed to get something done, most likely for much less than what that something is actually worth, while also being crushed by extremely high taxes that essentially doubles the cost of computer hardware.
