An interesting and provocative piece here. I'll just make a few comments/initial responses.
1. On white people at the airport. There are all kinds of foreigners who visit or come to stay in Nigeria. Quite a few are not lured by financial gain however. "NGO types" rarely get paid very much. There are foreigners who come and make good money in Nigeria, but perhaps not as many as people think. Meanwhile, many of the Nigerians you see at the same airport are economic migrants, returning home not for love of country, but motivated by the same financial gain. To be fair, a good many are also looking for opportunities racial glass ceilings denied them elsewhere.
2. Aid money. Aid money from Western governments is insignificant in the scheme of things. In most Western countries, its a fraction of 1% of the annual budget. Aid money into Nigeria is a meaninglessly small amount of the Nigerian budget. Donors have very little say in what goes on and are only given lip service. The big government spending decisions are made by Nigerians alone. Also, aid money to Africa is under threat right now thanks to most Western governments being heavily in debt. If Africa didn't exist, it wouldn't need to be invented right now.
3. The Angry African. I'm not sure many Africans are all that angry. Certainly, not enough are angry enough for the rest of the world to really take note. Far too few Africans are politicised. There is scant mobilisation or collaboration between different groups at play. Where there are angry Africans, they often work alone or are isolated and then alienated. This can create a shrill voice where exaggerations of the truth can fill in the gaps. And it can lead to its own forms of passivity and futility ultimately.
4. Africa of the past and future. If Africa is China's future (the Dambisa Moyo argument) we should all be worried. One only has to see how China does its internal repression (Tibet and elsewhere) to see that China is a strange sort of friend. China's real interest is to appropriate natural resources and increase the market for its shoddy goods, rather than develop Africa in any way.
One should also note that global warming and desertification is sadly going to hit many parts of Africa harder than elsewhere and is hardly a future to look forward to. Food and water security are set to become serious issues, as they already are in Niger. Better Internet access is going to take years to penetrate beyond the continent's large cities and towns. Increased power generation is decades away. The satellite image of the world at night that we have all seen will remain dark over Africa at least until the next generation.
5. How to read about Africa. There is another type of Western commentator on Africa Tolu doesn't refer to. These are the scholars of Africa. They often speak one or more African languages fluently. They have had access to information, analysis and other resources on Africa that most Africans have never seen, and in turn they create more information, analysis and resources. Some of them are even African. The scholarship on African society, economy and lived realities is much more extensive in the West than elsewhere. African philosophy, where it exists, takes place on American campuses. All that is to say: a key missing pillar of a publishing infrastructure is academia and the critical discourse it makes available.
My final thought. Africa should look to India perhaps more than anywhere else. The Indian sub-continent is more populous than Africa by around the population of Nigeria or perhaps more. India is engaged in many forms of internal conversation and doesn't look to the West for recognition or affirmation. India has excellent universities and a thriving internal publishing industry. It is not clear who the 'you' is in the title of Tolu's essay (I would imagine a pretty sophisticated readership for 3QD). However, its besides the point.
The African internal conversation is only just beginning. That's where the real action is at.
