That's a vague question. Africa is a huge continent with many nations of varying development stages. Some nations, such as South Africa and Morocco have fairly reasonable Internet penetration. I'm just reading that Burkina Faso
has 80% of the population using the Internet. At the other end of the scale we have countries such as Chad, Somalia and Eritrea who are well down on that scale.
Internet access is still growing around the world, although pretty much every government (regime) wants to censor Internet access in some shape or form (yes, even you "Land of the Free" primates are guilty of this) because education and knowledge enables people to see through the propaganda spread by all governments. This is a losing battle the governments engage in. We are an inquisitive species and attempting to stop the march on a desire to evolve (logically through education and knowledge) is akin to Cnut ordering the tides to retreat.
Power generation systems are currently undergoing a quantum leap, not least of all due to pioneers such as Elon Musk. I read recently that he plans to make the Tesla Superchargers 100% off-grid (Florida prohibits living off-grid - welcome to the Land of the Free) and this means nearly free electricity can be brought to so many impoverished parts of the world. Bring cheap/free energy and you remove the need for human labour. Allow people more free time to learn and grow mentally and good things happen. Especially when you allow women control over their own bodies and reproductive cycles.
Is Africa ready, you ask? Africa is, yes. But we all need to help bring Africa into the modern age and stop funding dictators in exchange for pillaging their nation's mineral wealth.
