It looks a bit like a vague meandering piece trying to drum up interest for their investment syndicate. The user that submitted this piece seems to be leading a syndicate based on Africa with the author [0].
Investment in Africa would be better served by listening more to underprivileged Africans that have not had access to the same opportunities and capital. Microfinance to support this demographic would be more effective and impactful than investing in an angel syndicate supported by these sort of blog posts.
Perhaps exploring solutions can yield better outcomes if exploring with the ones that will benefit from those solutions. For example, if you are trying to develop agriculture solutions for Africa, a blog post promoted on HN and Angel is unlikely to be read by a subsistence farmer in Africa.
There is a cottage industry of people claiming to do projects to help Africa. With marketing via blog posts geared towards those with access to capital, these projects can be funded. And since it is about Africa, there is less scrutiny about how effective it really is. Superficial facile accolades along with wining and dining at global events can further obfuscate this reality.
