Now if it is matched by an unprecedented growth, it may turn out OK. But if I was a young african male, I would try my luck in Europe.

If you were a young African male with the means of getting to Europe, there's at least half a dozen African countries where your economic prospects over the next 20-30 years would likely outstrip going to Europe unless you are in a tiny minority with skills that are in very high demand in Europe.
As it stands, they'd need to see a total catastrophic collapse of the economy of most of the African continent, with no subsequent recovery, for economic growth to not outpace population growth over the next few decades.
I'm sure you can't extrapolate it and assume it will stay the same for the next 30 years. But you can make reasonably educated estimates assuming that the average change in velocity will be all that extreme, given that large part of these amounts are based on income from relatively stable industries with well understood risk profiles.
Largely the development of Africa at present boils down to whether or not we see further major wars disrupt the progress. If we do, then, yes, things may go the wrong way. If not, it will take unprecedented crises to prevent Africa from continuing to see massive growth.
African demographic projections which shows Africa's population growth slowly dropping? Coupled with economic projections which shows most African economies growing at far faster rates than Europe? With some African countries, like Nigeria, likely to overtake the UK in total GDP (not per capita) over the next 20-30 years? Largely as a result of massively improved stability and fewer wars over the last decade.
Africa has plenty of challenges, but they're mostly headed the right way. And they're also slowly but steadily moving towards a far more ambitious union project than the EU, with several of the African Union pillars (regional closer unions like ECOWAS serves as "first stage" integration) hard at work at monetary unions and extensive integration.
Of course things can change - nobody expected Syria to blow up the way it did and more than we expected Yugoslavia to collapse as violently as it did.
But at the moment, countries like Nigeria are seeing graduates etc. returning in droves from the UK because the opportunities there are immense, cost of living low (though housing prices in parts of places like Lagos can rival London) and growth at levels you can't hope for in the UK.
